[Twisted-Python] Threading examples...

[stephan]

The following snippet is the code I use and it works for my needs. Be 
careful with  non-threadsafe code (db api, etc...) though.

==========
 from twisted.internet import threads

threads.deferToThread(aSillyBlockingMethod, x).addCallback(\
         writeRequestAndFinish, request)
=========

I am using this in a twisted webserver that is why I am registering the 
writeRequestAndFinish methode to finish up on the render  methode where
I returned server.NOT_DONE_YET. But you can register any callback or no
callback as well.
