Fix domain timer tests.
Fix UDP ref / unref tests.
Fix chmod for Java 7.
Fix HTTP parsing to properly handle pipelined requests that come in
one big chunk.
Exclude a few HTTP tests that are broken. Fix some more.
Re-factor processing for nextTick() to be closer to native Node.js.
Should be final round of excluding tests and fixing how they are run.
Goal is to get to zero failures, then we can assess code coverage and
re-enable tests as necessary.
Two more tests to exclude that fail in the cloud but not locally.
