3TODO: ABI??? API????? Changes??? 34.03 Tue Jan 11 14:37:25 CET 2011
4TODO: win32 write() to socket for signal handling 4 - officially support polling files with all backends.
5TODO: poll asert 5 - support files, /dev/zero etc. the same way as select in the epoll
6TODO: EV_USE__XXX default with config, document 6 backend, by generating events on our own.
7TODO: pendingall => idleall? 7 - ports backend: work around solaris bug 6874410 and many related ones
8TODO: portbality section, solaris errno rrentrant, aix, win32, linux 32 bit 8 (EINTR, maybe more), with no performance loss (note that the solaris
9TODO: include ev_xyz_start in each example? 9 bug report is actually wrong, reality is far more bizarre and broken
10TODO: section watcher states/lifetime 10 than that).
11 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
12 #ifdef to test for them.
13 - new (experimental) function: ev_feed_signal.
14 - new (to become default) EVFLAG_NOSIGMASK flag.
15 - new EVBACKEND_MASK symbol.

18 - automake fucked it up, apparently, --add-missing -f is not quite enough
19 to make it update its files, so 4.00 didn't install ev++.h and
20 event.h on make install. grrr.
21 - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
22 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
23 - use "(libev) " prefix for all libev error messages now.

41 - do async init within ev_async_start, not ev_async_set, which avoids
42 an API quirk where the set function must be called in the C++ API
43 even when there is nothing to set.
