You'll laugh at the results I got with the Macintosh ca - 36 seconds!  Looks like it's
not a real OS after all.

I have a suggestion to avoid all this magic number business (the 1 µsec threshold).  Why not 
simply accept a value of zero (0.0) in ca_pend_event/ca_pend_io to mean 'no extra delay'

Just a suggestion,
