I ran test/jdk/sun/tools/jhsdb about 300 times, basically enough times to at least reproduce the SIGILL failure once. I don't seem to see the SIGTRAP failure anymore.

ERROR: catch_mach_exception_raise: signal is not SIGSTOP (4)
ERROR: attach: wait_for_exception: catch_mach_exception_raise() got unknown exception type
ERROR: attach: wait_for_exception() failed. Retried 0 times
Error attaching to process: Can't attach to the process. Issues with reception of the exception message.
sun.jvm.hotspot.debugger.DebuggerException: Can't attach to the process. Issues with reception of the exception message.
