Test : nsk/regression/b4482614
TestBase : testbase_nsk
VM : Client VM, Server VM
Mode : mixed, comp
Platform : sparc
OS : Solaris 9, Solaris 10
----------------------------------------

This is a regression test for the bug
    4482614 (P3/S3) LINUX: process reaping is broken
    Release summary: merlin-beta
    Hardware version: generic
    O/S version (unbundled products): Linux

The test starts NUMBER_OF_THREADS threads, each thread then executes
"perl -version" command NUMBER_OF_PROCESSES times (perl is passed to the
test as an argument). The test defines timeout variable -- 80% of Tonga
TIMEOUT variable, but not less then 15 minutes.

After this time expires, the test checks if all threads are alive. If none
threads hang, isAlive() always return false. If any thread is hung,
isAlive() returns true. The test expects that all threads are dead after
that period of time. If so, it returns 95 (PASS).Otherwise, it returns 97
code (FAIL).

This failure is reproduced only on Solaris 9 and Solaris 10.
For all other OS the test passed, as well as for Solaris 8.
Actually NUMBER_OF_THREADS=10 and NUMBER_OF_PROCESSES=800.
If you reduce NUMBER_OF_PROCESSES to 200 the test will pass,
so I guess this is perfomance issue.

Steps to reproduce
================
1. cd /net/sqesvr.eng/export/vsn/GammaBase/Bugs/{BugID}
2. sh doit.sh $JAVA_HOME [-v] [timeout [perl [-options]]]

where JAVA_HOME should point to testable JDK
      -v produce verbose output
      timeout time to wait in minutes (default=15)
      perl point to perl (default=/usr/dist/exe/perl5)
      -options Java options
