So Rails 5.0 will require Symbol GC. It will support only Ruby 2.2\n+or later. (See [Rails' blog post](http://weblog.rubyonrails.org/2014/8/20/Rails-4-2-beta1/) for details.)\n+\n+Also, new Incremental GC decreases pause time of garbage collection.\n+It is helpful for running Rails applications.\n+\n+Another feature about memory management is adding a option to use jemalloc for configure.in.\n+[Feature #9113](https://bugs.ruby-lang.org/issues/9113)\n+This is experimental feature, and is disabled by default.\n+We need to gather use case and performance data.\n+After gathering them and we convince the benefit, it will be enabled by default.\n+\n+One more topic is [using vfork(2) in system() and spawn() (Japanese)](http://www.a-k-r.org/d/2014-09.html#a2014_09_06).\n+It is expected that it brings huge speed up when large process executes external commands many times.\n+But vfork(2) is risky system call.","path":"en/news/_posts/2014-11-25-ruby-2-2-0-preview2-released.md","position":32,"original_position":32,"commit_id":"9f65e98d18f367f78e8180b1fef9cd333628e7a4","original_commit_id":"9f65e98d18f367f78e8180b1fef9cd333628e7a4","user":{"login":"stomar","id":1112299,"avatar_url":"https://avatars.githubusercontent.com/u/1112299?v=3","gravatar_id":"","url":"https://api.github.com/users/stomar","html_url":"https://github.com/stomar","followers_url":"https://api.github.com/users/stomar/followers","following_url":"https://api.github.com/users/stomar/following{/other_user}","gists_url":"https://api.github.com/users/stomar/gists{/gist_id}","starred_url":"https://api.github.com/users/stomar/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/stomar/subscriptions","organizations_url":"https://api.github.com/users/stomar/orgs","repos_url":"https://api.github.com/users/stomar/repos","events_url":"https://api.github.com/users/stomar/events{/privacy}","received_events_url":"https://api.github.com/users/stomar/received_events","type":"User","site_admin":false},"body":"`is a risky`","created_at":"2014-11-25T14:20:11Z","updated_at":"2014-11-25T14:20:11Z","html_url":"https://github.com/ruby/www.ruby-lang.org/pull/901#discussion_r20864795","pull_request_url":"https://api.github.com/repos/ruby/www.ruby-lang.org/pulls/901","_links":{"self":{"href":"https://api.github.com/repos/ruby/www.ruby-lang.org/pulls/comments/20864795"},"html":{"href":"https://github.com/ruby/www.ruby-lang.org/pull/901#discussion_r20864795"},"pull_request":{"href":"https://api.github.com/repos/ruby/www.ruby-lang.org/pulls/901"}}},"pull_request":{"url":"https://api.github.com/repos/ruby/www.ruby-lang.org/pulls/901","id":24987261,"html_url":"https://github.com/ruby/www.ruby-lang.org/pull/901","diff_url":"https://github.com/ruby/www.ruby-lang.org/pull/901.diff","patch_url":"https://github.com/ruby/www.ruby-lang.org/pull/901.patch","issue_url":"https://api.github.com/repos/ruby/www.ruby-lang.org/issues/901","number":901,"state":"open","locked":false,"title":"Create 2014-11-25-ruby-2-2-0-preview2-released.md","user":{"login":"nurse","id":13423,"avatar_url":"https://avatars.githubusercontent.com/u/13423?v=3","gravatar_id":"","url":"https://api.github.com/users/nurse","html_url":"https://github.com/nurse","followers_url":"https://api.github.com/users/nurse/followers","following_url":"https://api.github.com/users/nurse/following{/other_user}","gists_url":"https://api.github.com/users/nurse/gists{/gist_id}","starred_url":"https://api.github.com/users/nurse/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/nurse/subscriptions","organizations_url":"https://api.github.com/users/nurse/orgs","repos_url":"https://api.github.com/users/nurse/repos","events_url":"https://api.github.com/users/nurse/events{/privacy}","received_events_url":"https://api.github.com/users/nurse/received_events","type":"User","site_admin":false},"body":"This is still draft.
