python .../test/test_thread.py shows that time.sleep()
does not relinquish the processor.
As one thread goes to sleep, another thread ought
to start processing.   That doesn't happen.

Python was configured with --with-thread
and compiler flags -mt and -D_REENTRANT.
See line from config.status: s%@CC@%cc -mt -D_REENTRANT%g

EXAMPLE:

hce* python test_thread.py
creating task 1
creating task 2
creating task 3
creating task 4
creating task 5
creating task 6
creating task 7
creating task 8
creating task 9
creating task 10
waiting for all tasks to complete
task 1 will run for 9.9 sec		# goes to sleep here...
task 1 done				# 9.9 seconds later...
task 5 will run for 4.1 sec		# This should have started when task 1 slept.
task 5 done
task 7 will run for 9.9 sec
task 7 done
task 4 will run for 9.2 sec
task 4 done
task task 6 will run for 7.7 sec
