Yet Another Asynchronous Python Comet Library, of interest because this is the first one I’ve seen that uses Python’s generator coroutines, taking advantage of the return value of the yield statement to feed messages in to a generator function. Currently only works on Python 2.6 on Linux due to a dependency on 2.6’s epoll support. # 23rd September 2009, 5:15 pm
