Windows does not show this. We have only been running this on Linux
ES/AS 3.0+ and Solaris 9+ (Sparc), and do see it on those platforms,
as far as I know, they behave identically.

I'll provide whatever information you think might be helpful.

For what it's worth, in case it wasn't clear, it is not our intention
to have the mutex remain locked if there are no longer any processes
running. When the last process using the mutex is running, we'd like
the mutex to unlock or even disappear entirely. The problem is that
it remains locked, apparently due to the existence of the file.
