* This is a companion DTrace script that is used by the sleep test. It
* checks if the executed program asks to sleep for the right amount of
* time and then exits in a way to indicate this. At the same time, it
* always uses the SIGALRM feature of sleep(1) to make sure that sleep
* doesn't continue executing (and also to make sure that the feature
* works).
*
* We expect the number of seconds in $1 and the number of nanoseconds
* in $2. This script should be invoked as dtrace -s sleep.d -c
* '/usr/bin/sleep <waittime>' <seconds> <nanoseconds>.
