js/dom/create-lots-of-workers.html frequently crashes, spawning an extreme number of threads. This is sometimes reported for this tests, and sometimes for the next one, js/dom/cross-frame-bad-time.html.
There are only 100 workers, but >2000 threads: <http://build.webkit.org/results/Apple%20MountainLion%20Debug%20WK1%20(Tests)/r165119%20(13072)/js/dom/cross-frame-bad-time-crash-log.txt>.

I count at least 261 workers in the crash log, but you're right, this is a little crazy. We spawn ~6 GC threads and 1 block freeing thread per VM (along with the main worker thread).

Skipped the test in <http://trac.webkit.org/r165360>, as it was making bots very red.
A fix would be appreciated, we don't have a lot of workers tests to skip.
