Freeing a subpool is against my religious principles: I'm a devout coward, and 
look to Finagle as a prophet. There are too many ways for things to go pear 
shaped.

Subject: Re: How do I choose a subpool?

You know what? I've decided to take @Rob's advice and do individual FREEMAINs 
one at a time. The code is going to run in a variety of shared ISPF and 
Websphere environments. No matter what subpool I choose, there is just no way 
of knowing that another programmer hasn't chosen to use the same subpool. Worst 
case doing individual FREEMAINs I will mess up his or her usage statistics. But 
doing subpool FREEMAINs, worst case I make a real mess.

IMHO subpools would have been a lot more useful if there were a way to reserve 
one, or at least to check (yes, TOCTOU issues) for an unused one.

At the very least the world could use a "Cheryl SMF list" of known subpool 
utilizations.
