Connection Pool with Erlang PB Client Necessary?

Thanks for all the replies guys!

I just want to make sure I'm totally clear on this.  Bob's solution
would work well with my design.  So basically, this would be the

1.  check out connection from the pool
2.  set client id on connection (which would have some static and some
random component)
3.  perform multiple operations (gets, puts, etc.) which would be seen
as a single "transaction"
4.  check in the connection to the pool

This way once the connection is checked out from the pool, if another
user comes along he cannot get that same connection until it has been
checked back in, which would meet Justin's requirements.  However,
each time it's checked out, a new client id is created.

Does this sound reasonable and in line with proper client id usage?

Thanks again!
