Re: Threads and DRb
Brian,
I slept over it and came up with this pool implementation (see attachment).
The facade part is still missing, but I've no experience with drb so I guess
that's the part where you can give better input.

Sounds reasonable but not feasible with a separated pool. My pool does it
on insertion and retrieval. Maybe this should be changed if we assume that
instances don't change their state in the pool. Then checking on reinsert
should be sufficient.
One could adhere to the pattern that an instance is only put back into the
pool if the method did not throw. This is easy achieved by changing the
pattern
obj = pool.get
begin
obj.do()
ensure
pool.put obj
end
to
obj = pool.get
obj.do()
pool.put obj
which will omit the put() in case of an exception.

Well, just hand the pool over to the facade on construction or create it in
initialize().

No, as I said this can't happen in your example. But the more general
pattern is to repeat the check. That's not too costly and you avoid strange
errors if the condition variable is used for other signals. (I can't see
such an application yet, and maybe I'm too much influenced by the Java
notify() and notifyAll()...)
I think the situation changes with a separated pool: In that case you want
to limit the number of threads that is concurrently running. In that case
the pool does not need a condition variable (see my example). Instead the
facade instance needs a semaphore which is initialized to the max amount of
threads and decremented on entry and incremented on exit of a method.

Thanks! I'm not satisfied with it yet, but I try to add something from time
to time.

=Class InstancePool
This class maintains a thread safe pool of instances.
Instances are obtained via ((<InstancePool#get>)) and
put back via ((<InstancePool#put>)). These operations
are thread safe.
New instances are created via the factory code handed to
the constructor as block.
