 Revision history for libev, a high-performance and full-featured event loop.
 
 TODO: revisit 59.x timer in the light of modern powersaving
-TODO: maybe use timerfd to detect time jumps on linux
 TODO: document EV_TSTAMP_T

-TODO: use TFD_TIMER_CANCEL_ON_SET to call periodics_reschedule, maybe? (must)

 	- handle backends with minimum wait time a bit better by not
           waiting in the presence of already-expired timers
           (behaviour reported by Felipe Gasper).

 example) that can't properly initialise their signal masks.
