I am not a perl expert, but you would probably have to use the fork()
command. The following is copied almost verbatim from the "Camel Book"
(Larry Wall, Tom Christiansen & Randal L. Schwartz, Programming Perl,
O'Reilly, 2nd edition, 1996).

FORK: {
   if ($pid = fork) {
      # continue parent process
      # pid of child process is in $pid
   } elsif (defined $pid) {
      exec "fetchnews -vv"
      # not reached
   } elsif ($! =~ /No more process/) {
      # EAGAIN, supposedly recoverable fork error
      sleep 5;
      redo FORK;
   } else {
      # weird fork error
      die "Can't fork: $!\n"
   }
}

(Disclaimer: I have not tried this.)
