Aah.  So what you're saying is you want an API which multiple
thread-pools can communicate via to establish a suggested minimum value
for the maximum thread count?

I'm not opposed to such a thing, but shouldn't this be a deployment /
tuning option particular to a configuration?  The suggested value would
have to be a fairly subtle hint...

Maybe something like
addtlThreadCount)'?  The reactor could track the suggesting object with
a weakref to decrease the total thread count when it goes away.
