Bug description:usleep prevents script timeout
Description:
------------
Usleeped time does not count in total timeout time.
Commenting out line 11 "usleep(10)" in the test script results with
expected
Fatal timeout in 2 seconds.
Enabling line 11 "usleep(10)" makes script exit by condition in 50
seconds.
Increasing waiting time to 100 seconds in line 2 results with timeout Fatal
error in 60-70 sec.
