HotSpot 1.4.0-rc-b91 fails to pass the following test

nsk/hprof/options/monitor/monitor005

from testbase_nsk on all platforms in all VM modes. The VM crashes with
segmentation fault. Simetimes I also observe that on Linux platform VM's
process hangs after VM crash, and if it happens, the process can be killed
only by sending the KILL signal.

The test performs simple check that HPROF profiler agent can obtain
CPU usage and monitor contention information, being run with the options
"cpu=samples,monitor=y".

To reproduce the bug run with HS1.4

sh doit.sh $JAVA_HOME

in
/net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/<this bug number>

where JAVA_HOME should point to jdk1.4.0
