It is limited by CPU horsepower and memory.

No, there is a single thread for the Transaction FSM. Additionally, I  
don't think "UNIX" has a 256 thread limit. Certainly linux has no  
such limit. Moreover, creating a thread per-call would be a very  
naive thread architecture; so there is no danger of us doing that any  
time soon. What flavor of UNIX limits you to 256 threads?
