ThreadPoolc B� s5 e Z d Z d d d � Z d d d � Z d � Z RS( u%
This is a very VERY basic threadpool implementation
This was made instead of using multiprocessing ThreadPool because
we want to set max queue size and we want to daemonize threads (neither
is exposed in the stdlib version).
Since there isn't much use for this class as of right now this implementation
Only supports daemonized threads and will *not* return results
TODO: if this is found to be more generally useful it would be nice to pull
in the majority of code from upstream or from http://bit.ly/1wTeJtM
