The time.awk test does a sleep() and verifies that the actual delay is
close to the requested time. However on a loaded system the range of
acceptable durations is quite tight and will occasionally fail.
Solve this by increasing the range of acceptable delays slightly to
between 50% and 200% of the requested delay.
