Ah, good with conclusive proof.
In the meantime I found out about the timer features of ALSA.

Unless I'm missing something (which I very well might be) it seems to work
regardless. Perhaps it uses the HPET?
It also seems to work on PPC/Linux which solves another issue. I'm in the
middle of trying to implement it in MusE, I guess I'll see if it works.
Which leads to the following question I've been asking myself for some time:
the ALSA sequencer API seems to allow *timestamped* events - you put such
an event in a queue and it will appear at the other end at the right moment.
If this is true, and if ALSA has an high precision timer available to
implement it, why should apps like MusE bother to do the fine timing
themselves ?
