Hehe, I had started to ask about that but figured something out as I was
writing that message, so I recycled it to ask about timing.. but I
obviously forgot to change the subject :)

That's ok, I'm only after a way to wait for 25 50ths of a second and stuff
like that.

Hmm, ok, but how would I get the 64 bit value of the eclock? I guess
maybe only the lower 32 bits are going to change in a second or two
anyway?
