yes

mplayer has 3 ways to timer:
1. RTC (hw timer)
2. usleep() (10ms resolution under linux, bad)
3. -softsleep (optional, disabled by default) - busy looping... (cpu burn:))

> This timer has a much higher resolution and is similar to usleep()

good idea.
add #ifdef'ed cygwin code to linux/timer-lx.c::usec_sleep()
(and don't be confused by dir/filename, it should be named osdep/timer.c :))
