It could be; if OS X is processing a dlclose() for the mechglue, and
that results in a dlclose() of another shared object which has the
mechglue as a dependency... it could easily screw up and call the
finalizer again.

I'm okay with working around this apparent bug in the manner you
suggested (setting did-run to 0) if it's easy.
