Committed, thanks.

Basically: use msleep(). It allows other tasks to be scheduled while the
process is doing nothing. udelay() is meant to be used when the hardware needs
a precise amount of time, since it runs a do-nothing loop. Also, msleep may
eat less power, since processor can reduce its power consumption if there's
nothing to be scheduled.

Cheers,
Mauro
