where the code uses a pid (getpid()) you need to use a concatenation of
pid and thread id.

otherwise you violate some of the uniqueness guarantees.

i just didn't bother trying to figure out how to get a thread id in any
sort of portable way and left that to folks who actually wanted the module
on those platforms.

(this is actually mentioned in the comments near the top of the file
describing how it works and the assumptions made.)
