Comment (by cus):

 IMHO SRT should be fixed instead to support srt_startup() srt_cleanup()
 cycles properly. What is the purpose of reference counting if
 srt_cleanup() can only be called at the very end of an application? It
 does not make a lot of sense.

 Clearly it is not OK to call srt_startup() in any of the global init
 functions (which are by the way depreacated), because nobody wants the srt
 library to spawn a thread when it is not even known that if srt will be
 used at all.

 Meanwhile you can call srt_startup() yourself from your application before
 doing any work. This will keep the reference counter above 0, so global
 state should never be destroyed.
