[ruby-talk:14526] Re: who uses Python or Ruby, and for what?

An object pool is a "container" that manages a series
of pre-instantiated objects.  In circumstances such as
databases you dont always want to create a connection
to the database every single time a user needs to do
some database work. Rather, you create a pool of
database objects with pre-instantiated connections
that logical users can then request, use, and then
return to a pool.

Pools often have a minimum and maximum number of
objects they can hold, and grow from the min to max
number of objects as required.

This is a very generalized version, but I hope it
makes sense. With object pools you start working into
threaded pools and weak references, and other funky
stuff. They can get really elaborate using proxies and
other things.

Hope that helps,

Bryan
