Revision: 58075 (and later)

When invoked from <CHROMIUM>/src/webkit/tools/layout_tests/run_webkit_tests.py,
WebKitTools/Scripts/new-run-webkit-tests hangs until it times out after 600
seconds.

I observed this both in my local (Chromium) environment:
  ./webkit/tools/layout_tests/run_webkit_tests.py  --debug fast/[a-b]*
--verbose
and in Chromium's canary bots:
 
http://build.chromium.org/buildbot/waterfall.fyi/waterfall?builder=Webkit+Mac+(webkit.org)
  (Sometimes the tests go through, sometimes hang.)

As far as I tested, the hang is not caused by a specific test(s) -- the test
being run by the
hanging thread differs every time I tried (a few dozen times).
