Revision history for libev, a high-performance and full-featured event loop.
+ - fix a bug where an inotify watcher was added twice, causing
+ freezes on hash collisions.
- new config symbol, EV_USE_CLOCK_SYSCALL, to make libev use
a direct syscall - slower, but no dependency on librt et al.
- assume negative return values != -1 signals success of port_getn

- fixed const object callbacks in ev++.h.
- replaced loop_ref argument of watcher.set (loop) by a direct
ev_loop * in ev++.h, to avoid clashes with functor patch.
+ - do not try to watch the empty string via inotify.
