[drlvm][gc_gen] Thread termination in thread.SmallStackThreadTest is terribly slow
----------------------------------------------------------------------------------

                 Key: HARMONY-4601
                 URL: https://issues.apache.org/jira/browse/HARMONY-4601
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Linux/ia32
            Reporter: Gregory Shimansky


The test creates a big number of threads (4000) that mostly do nothing. Threads are waiting
and then are joined by the main thread. This mostly doesn't consume CPU on the machine. But
then all of these threads go through gc_thread_kill function. It executes thread deletion
from a list under a global spin-lock, so all 4000 threads are waiting on it using CPU at the
same time since the lock spins inside of the loop.

This test usually doesn't finish on linux/ia32 (for some reason it works on other platforms)
and times out. So I created this bug report to exclude it.
