Example of breakage we've got: http://chromegw.corp.google.com/i/chromium/builders/Vista%20Tests%20%28dbg%29%285%29/builds/7184

It only affected Vista browser_tests, on couple of bots. The symptom was that test just hangs w/o any info in stdio.

I couldn't reproduce this problem on Vista Business SP2.
I'll try Valgrind or ASAN.

We couldn't get to a better diagnostic, but failures repeated for 3 cycles in a row and revert did help...

Sometimes it's hard to reproduce on local machines but reproduces on bots (timing?) It is possible to run Chrome try job with WK patch. Ping me for instructions if needed.

But we have no Vista try server.

I tested with r89407 change on Linux Valgrind, Linux ASAN, Mac Valgrind, and found no new errors.

I'll try to split the patch, and make it a little safer, then try landing again.

I re-landed the r89407 change, and it seems it didn't cause the problem on Vista!

Great! Sorry about the trouble, our test flakiness is still high, unfortunately...
