This bug was encountered while chasing the following bug:

4369489 2/5 jdb does not work on Linux platform.

This bug is the sixth layer of that onion.

The SuspendCheckerThread is not working right on Linux. This prevents
the VMThread from detecting suspend operations that will hang itself.

EVALUATION daniel.daugherty@Eng 2001-03-27 There are a couple of problems: - The VMThread tries to use the SuspendCheckThread before it is ready; this is a timing problem from my original implementation that only showed up with slower Linux thread launching. - The VMThread/SuspendCheckerThread deadlock detection is not working; this is a bug with Monitor::wait() where the timeout is not detected on Linux. See linux-hang0.log for analysis of the hang.
