Jonathan,

Thanks for the advice but would like to pick your brain a little more.
The pool I need is not a thread pool or db pool. I need to pool
objects which are a proxy for an external C process that communicates
via sockets. The pool is necessary because the initial connection/
authentication is expensive, plus the connection needs to be recycled
every so often due to instability on the C side. The existing Java
code uses commons-pool which incidentally is the base object pool for
a db connection pooling library (DBCP). Anyway, maybe this is just so
easy to do in Python that everyone rolls their own - but I have done a
lot of googling with no luck.

I just hate to re-invent the wheel here - I guess I should look at a
db connection pooling library and see if they have a generic object
pool somewhere in there. Any you can recommend that are more or less
standalone db connection pool libraries ?

Thanks,
Rick
