This makes sense.

Attempting  delay of 10000000 nsec (10000 usecs)
gettimeofday reported delay  =  11019 usecs
Actual usec delay from timer =  10952 usecs

Attempting  delay of 20000000 nsec (20000 usecs)
gettimeofday reported delay  =  21033 usecs
Actual usec delay from timer =  20963 usecs

Attempting  delay of 40000000 nsec (40000 usecs)
gettimeofday reported delay  =  41298 usecs
Actual usec delay from timer =  41234 usecs

nanosleep does not relinquish the cpu. Using it in my env causes
serious problems.

I guess the nsec member of the timeval struct was misleading me. I
should have known better.
