The current process is suspended from execution for the number

of seconds specified by the argument.
|

The routine is implemented by setting an alarm timer
|
|
and pausing until it occurs.
|
|
The previous state of this timer is saved and restored.
|
|
If the sleep time exceeds the time to the expiration of the
|
|
previous timer,
|
|
the process sleeps only until the signal would have occurred, and the
|
|
signal is sent 1 second later.
