<para>
This command puts the user's process to &quot;sleep&quot; for a number of
clock ticks. It is generally used to generate time delays or to
&quot;break up&quot; CPU-intensive jobs. The duration of a tick is 16.66
milliseconds.
</para>
<para>
A tick count of 1 causes the process to &quot;give up&quot; its current time
slide. A tick count of zero causes the process to sleep
indefinitely (usually awakened by a signal)
