Does anyone have an explanation for the following bizarre (but verified) 
data regarding SR's and CPU usage on the OLPC? My test .csd is with 
ksmps=10, realtime, with MIDI input.

SR=44100: Csound CPU usage = 26%, total CPU usage = 54%
(SR=48000: 32% and 52%)
SR=36000: 4% and 6%
SR=32000: 3% and 5%
SR=22050: <3% and 4%

All conditions, to my knowledge, except for SR, were identical.

It makes no sense to me, but the difference is real. I'll be using SR=32000 
or 36000 instead of 44100.

Whatever the reason, I'll now be able to port *some* of what I'd hoped to 
the OLPC.
