Unfortunately, I never found a solution. In my situation the problem
was exacerbated by the fact that the main program loaded each plug-in
into it's own thread. FWIW, I ended up, due to timing constraints,
converting the dynamic module into an "agent" that communicated with a
separate process, a ruby server written in ruby. Not for every
situation, pretty, or efficient, but it bought me some time.

When I tired the patch in 2294, it delayed the crash but didn't
eliminate it. I see that Suraj has made a few updates since I last
tried it. It is worth a try since it worked for some people. I hope to
try the latest patch soon and update the issue with my findings.
