FatalError [13] Unexpected issues while starting new thread for test javasoft.sqe.tests.api.java.lang.Thread.SleepDuration_positiveMs. Error: unable to create native thread: possibly out of memory or process/resource limits reached


The tail of stress stdout is:
For random generator using seed: 1052072573885100046
To re-run test with same seed value please add "-Djdk.test.lib.random.seed=1052072573885100046" to command line.
Stress process main method is started.

<snip>

result: Failed. Unexpected exit from test [exit code: 74]

I'm starting this bug in hotspot/test so that [~lmesnik] can take a
look at this failure mode which is rather strange.
