This is a proposed solution to #191
application if any thread-aware libevent functions are called BEFORE the
evthread API has been initialized (manually, or through
evthread_use_windows_threads() / evthread_use_pthreads()
'event_debug_created_threadable_ctx_' whenever the following functions
are called:
evthreadimpl_lock_alloc_()
evthreadimpl_cond_alloc_()
event_base_new_with_config()
(since this checks to see if the threadcallbacks are enabled, we have to manually set the variable)
When executed, the program will throw an error and exit:
[err] evthread initialization must be called BEFORE anything else!
I will spend more time looking for other entry points I might have missed.
