That's not totally correct. Both UHCI flavours have the means for
asynchronous unlinking (there's a flag for that), ie. it schedules the
unlink and returns immediately.
AFAIK (haven't looked at >2.3.99-pre6) OHCI is missing this feature.
It would see this as a urgent task before 2.4 comes out, any volunteers? ;-)
