Regarding the choice of which task will get the semahore if more than
one is waiting, I will for now assume that this is (intentionally) left
unspecified. This means I will have to implement FIFO order on top of
epicsEvent. The only other solution would be to extend the interface
with another constructor and then implement FIFO order *inside*
epicsEvent for those systems that do not support that natively (which
is what you wrote above, so maybe you *did* get the point I was trying
to make and I didn't get yours. Whatever ;-).

My current idea is to wait for your FIFO implementation and then see if that can be moved into epicsEvent... ;-)
