What kind of work are you queuing? If it's e.g. fetching a web page, you
can just use do it using Twisted's scalable asynchronous APIs (maybe
using a DeferredSemaphore if you want to limit number of conccurent
queries.) If it's a blocking API you're calling (RDBMS queries are the
typical example) then Twisted has a thread pool, as  well as
RDBMS-specific wrapper - see our documentation.
