Yes, if we could find a way to do the transition, I think we'd want to
transition to a library that supports only the safe interfaces and can't
do the wrong thing.  I just don't know how to do the transition.

I think the OpenAFS com_err adds locking in yet another different way, and
I'm not sure if something that just relies on pthreads would be sufficient
in OpenAFS (there's all that LWP stuff still in there, but I don't know
how it influences this problem).
