We are getting over 900 "OkHttp ConnectionPool" threads running at any given time running in state "TIMED_WAITING".  This is a large corporate installation so we have a lot of builds running at any given time but only a handful of repo hosted on Github maybe 5 an hours so there is no reason we should have that many threads running for this plugin.  The server also is experiencing a once a week can't create new thread errors which I believe is caused by OkHttp using up all the thread counts.
