Hello all,

I'd like to use a socket based bufferevent to perform asynchronous writing to 
the underlying socket:
One thread, X, adds data to the output  evbuffer (either by 
evbuffer_reserve_space+ evbuffer_commit_space or by evbuffer_add_reference) and 
another thread, Y, dispatches on the bufferevent's event_base (i.e., actually 
sends the data via the socket).
My questions are -
Does thread X need to perform locking on the evbuffer?
If so then how can I have thread Y synchronize on the same locks?
I assume that setting the bufferevent option BEV_OPT_THREADSAFE will not affect 
the "direct" access to  the evbuffer by X.

Thanks,
Avi
