TODO: not_blocked flag.
-TODO: ev_sleep suffers from different backend_fudge...
- correct backend_fudge for most backends, and implement a windows
specific workaround to avoid looping because we call both
select and Sleep, both with different time resolutions.
- document range and guarantees of ev_sleep.
+ - document reasonable ranges for periodics interval and offset.
+ - rename backend_fudge to backend_mintime to avoid future confusion :)
- change the default periodic reschedule function to hopefully be more
exact and correct even in corner cases or in the far future.
- - document reasonable ranges for periodics interval and offset.
- do not rely on -lm anymore: use it when available but use our
own floor () if it is missing. This should make it easier to embed,
as no external libraries are required.
