- wait

  Behaves like wait(2) 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 `$?` and `${^CHILD_ERROR_NATIVE}` . Note that a return value of `-1` could mean that child processes are being automatically reaped, as described in perlipc.

  If you use `wait` in your handler for $SIG{CHLD}, it may accidentally wait for the child created by qx() or system(). See perlipc for details.

  Portability issues: wait in perlport.
