Gregory Shimansky commented on HARMONY-2963:
--------------------------------------------

To run this test more reliably so that it doesn't crash VM but gets to the end and hang it is better to use single CPU computers. Otherwise different threads usually hit out of C heap condition and VM dies before test gets to shutdown stage.

> When running MegaSpawn test from HARMONY-2803 on windows and linux, if this test doesn't kill VM, it hangs at the end in some dead lock of 2 or more threads. This bug doesn't seem to be related to the stressing nature of the test, so it should be something different. It is likely that this is the same IO dead lock which makes stress.Mix to hang when it is running from "build test".
