I sort of worry about the naming collision with the term posix-clock, as
this is just one type of posix clock (I suspect most folks think of a
posix clock as the clockid passed to the existing posix api).
Could we maybe use posix-dynclock or posix-fdclock or something? I know
its already been changed from clkdev, so sorry for being finicky here
and not catching this earlier.
thanks
