I assume you have looked at pools for excalibur? You could use them as basis 
of such a pool. 

Let me see if I get what you want. You have pools 1-9 and they are associated 
with contexts 1-9. Each time you access pool you access the pool coresponding 
to you context? If so I have heard others want this functionality, and 
another version of this is using String version where you acess pool based on 
name. I guess you would call that MappedPool or similar.
