Hi,

I've made three patches to improve conversion between timing units, like 
sbintime, and usecs and so on.

I've been testing these for some days and can see a notiable difference 
when using realtime audio applications, in the form of less jitter, 
audio/hpsjam and video-chat using www/firefox .
