Changes for version 4.22
- (libev) when epoll detects unremovable fds in the fd set, rebuild only the epoll descriptor, not the signal pipe, to avoid SIGPIPE in ev_async_send. This doesn't solve it on fork, so document what needs to be done in ev_loop_fork (analyzed by Benjamin Mahler).
- (libev) remove superfluous sys/timeb.h include on win32 (analyzed by Jason Madden).
- updated libecb.
- libev - a high performance full-featured event loop written in C
