I have another thread that sometimes needs to inject commands, that uses esl_send_recv() on the same handle.
It looks like on occasion, both get stuck and stop receiving events.
Is it possible for two threads to access the handle? maybe I should open two connections to freeswitch esl? or use esl_send_recv_timed()?
