A system($cmd) call essentially does this:
defined($pid = fork) || die "Couldn't fork\n";
exec($cmd) unless $pid; # in child, exec() command
wait; # in parent, wait for child to finish
To have a status window, you need to have the parent keep running instead
of waiting for the child. So you have to do the fork business yourself.
Read perldoc perlipc, and read the examples in the Camel and Ram books.
