it really starts being ugly and inefficient

just a few questions:
- I don't think you need the enable_crst, do you ? I don't think the 
ioctl will be done in parallel anyway
- why do you need to change the message order ? you'd better in wave 
capture, when you run out of waveheaders try to process the pending 
messages (as we do in wave playback) before sending back an error, 
without reordering them

A+
