JDK : JDK1.4.2-b21
Testbase : RegTest-cte
Platform[s] : Solaris 9 (x86) (CDE), SMP, 4 CPUs (unable to reproduce on single-CPU box).
switch/Mode : -server
Falling test[s]: CTE_REGTEST/Generic/4820217/StreamsSurviveDestroy.java

The test performs 4 steps: test(), testCloseBeforeDestroy(), testCloseAfterDestroy(), testInterrupt()
and there is an intermittent failure in the testCloseAfterDestroy().

Most probably the failure is caused by the racing in the test (see also output logs below):
the stream copiers receive EOF from the process' output and error streams and stop working before
the test calls Process.destroy(), so the test fails.

Please note, that the failure is intermittent, and I was not able to reproduce it on my single-cpu
solx86 box after 10 runs.
