Don't introduce new parameter for resolve_redirect
Merge pull request #598 from untitaker/redirect_client

Don't introduce new parameter for resolve_redirect
Mention timeout unit in contrib.cache

Fix #599
Test both reloader types
Add testcase
Also scan sys.path
Explicitly assert reload

Also fails without this.
Make _recursive_walk actually recursive
Don't use simple sleep when waiting for reloader
Don't wait for reloader twice
Better dealing with invalid dirpaths
Install less watches
Parameter tuning and better error reporting
Wait for one loop round of the observer thread
