Libevent Wishlist

(I'm using this page to keep track of

Stuff Nick really wants in 2.1 or later:

• UDP "bufferevents".
• signalfd support on Linux - https://github.com/libevent/libevent/pull/1342 - DONE
• EVFILT_USER support on kqueue platforms.
• Drop-in support for other DNS resolver implementations.
• A better Windows backend based on IOCP, WSAEventSelect, and RegisterWaitForSingleObject. This is nontrivial, since the semantics of FD_WRITE in WSAEventSelect don't actually let you emulate EV_WRITE directly. Code to look at here includes libunbound and Chris Davis's hybrid-loop stuff. (Chris has a solution that just uses select for sockets. libunbound requires the caller to explicitly say when they have gotten WSAEWOULDBLOCK on a socket.)
• Better benchmarks, ideally based on sane loads.
• More detailed benchmarks for particular weird corner-cases.
• Fix the stupidness of our use of conditions to avoid event_del() races.
• A better solution than "deferred callbacks" to avoid callback circularity. (Partially done in 21_event_callback)
• A solution to the openssl-bufferevent deadlock issue.
• An NSPR-backed bufferevent implementation for people who prefer their TLS to be NSS-flavored.
• Monotonic time on more platforms.
