Okay, I'm offically confused then. I thought the PID
was unique among active connections. Then wouldn't the
hash be accessible from multiple processes and not
just one? Or does the shared library get loaded
separately for each process? If so, then there is no
need at all for a hash table, and a simple global int
would do. Maybe the whole thing is just overkill.
