First test CD:
nanosleep delays the execution of the program for at least
the time specified in *req. The function can return ear<AD>
lier if a signal has been delivered to the process. In
this case, it returns -1, sets errno to EINTR, and writes
Note the <AD> (shows up inverse video)
Setting LC_ALL=en_US (or en_GB :-) is reported to fix this problem.
