Have you noticed db connection sharing between processes?

The DB API stores for each connection the PID of the process opening it. 
When a process is asking for a db connection and URL matches and 
existing one, current PID is checked with connection pid and if they 
differ, a new connection should be created, thus no connection sharing 
should be between processes. Is the db connection open in main process 
used in other processes?

Cheers,
Daniel
