Hash :b77d3e78 Message :Epoll ET setting lost with multiple events for same fd
After two or more events have been registered for the same file
descriptor using EV_ET, if one of the events is deleted, then the
epoll_ctl() call issued by libevent drops the EPOLLET flag resulting in
level triggered notifications.
[ azat: use existing "et" in the evmap_io_del_() ]
