Woah. Never knew this was in Python.

It is quite interesting, as there is a very similar concept within Apache.
In that model, you register a cleanup function for the particular data that
needs to be cleaned post-fork. After the fork occurs, the cleanups are
called.

In essence, Python would register PyOS_AfterFork. Of course, any schmoe can
call fork() and avoid the cleanups, so it bungs up the whole scheme. In
Apache, the "only" way to fork is to call an APR function, which guarantees
the cleanups.

Cheers,
