wait
Behaves like the wait(2) system call on your system: it waits for a child
process to terminate and returns the pid of the deceased process, or
-1 if there are no child processes. The status is returned in $?.
Note that a return value of -1 could mean that child processes are
being automatically reaped, as described in the perlipc manpage.
