My code is essentially single-threaded.
However, sometimes it happens that in callback of one bufferevent I 
decide to stop processing another bufferevent and thus free up tied 
resources. In this case if something has already happened on abandoned 
bufferevent and waits till eventloop invokes its callback I would like 
to skip these invocations somehow.

As far as I understand this remark is related to multi-threaded usage 
which is not the case.
