6 - correct backend_fudge for most backends, and implement a windows
7 specific workaround to avoid looping because we call both
8 select and Sleep, both with different time resolutions.
9 - document range and guarantees of ev_sleep.
10 - document reasonable ranges for periodics interval and offset.
11 - rename backend_fudge to backend_mintime to avoid future confusion :)
12 - change the default periodic reschedule function to hopefully be more
13 exact and correct even in corner cases or in the far future.
14 - do not rely on -lm anymore: use it when available but use our
15 own floor () if it is missing. This should make it easier to embed,
16 as no external libraries are required.
17 - strategically import macros from libecb and mark rarely-used functions
18 as cache-chold (saving almost 2k code size on typical amd64 setups).

21 - fix two problems in the native win32 backend, where reuse of fd's
22 with different underlying handles caused handles not to be removed
23 or added to the select set (analyzed and tested by Bert Belder).
24 - do no rely on ceil() in ev_e?poll.c.
25 - backport libev to HP-UX versions before 11 v3.
26 - configure did not detect nanosleep and clock_gettime properly when
27 they are available in the libc (as opposed to -lrt).

30 - officially support polling files with all backends.
31 - support files, /dev/zero etc. the same way as select in the epoll
32 backend, by generating events on our own.
33 - ports backend: work around solaris bug 6874410 and many related ones
34 (EINTR, maybe more), with no performance loss (note that the solaris
35 bug report is actually wrong, reality is far more bizarre and broken
36 than that).
37 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
38 #ifdef to test for them.
39 - new (experimental) function: ev_feed_signal.
40 - new (to become default) EVFLAG_NOSIGMASK flag.
41 - new EVBACKEND_MASK symbol.
42 - updated COMMON IDIOMS SECTION.
43
444.01 Fri Nov 5 21:51:29 CET 2010
45 - automake fucked it up, apparently, --add-missing -f is not quite enough
46 to make it update its files, so 4.00 didn't install ev++.h and
47 event.h on make install. grrr.
48 - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
49 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
50 - use "(libev) " prefix for all libev error messages now.
