In Squeak, HTTP requests for _different_ sessions are processed 
concurrently via green threads (a thread is forked for each HTTP 
request). HTTP requests for the _same_ session are serialized via a 
session-specific Semaphore.

You do not _have_ to run multiple vms to handle concurrent requests in 

Hope this helps,
