Crochet is an MIT-licensed library that makes it easier for blocking and threaded applications like Flask or Django to use the Twisted networking framework.
Here's an example of a program using Crochet. Notice that you get a completely blocking interface to Twisted and do not need to run the Twisted reactor, the event loop, yourself.
../examples/blockingdns.py
Run on the command line:
$ python blockingdns.py twistedmatrix.com
