perldoc -f waitpid. For that matter, perl's system() waits for the child
process to exit before returning...

If you mean you want to wait for the child process to start running, but not
neccessarily for it to exit before the parent continues, perhaps opening a
pipe and have the child write to it while the parent blocks waiting to read
from it?
