Erh, fork already returns the child's pid (to the parent, if succesful). There is absolutely no need to increment it. If there is, your operating system is seriously broken.
if (my $pid = fork) {
# parent
} elsif (defined $pid) {
# child
exit;
} else {
# error
}
Some style issues: Don't use &foo: use foo() instead. &foo has some unpleasant side effects (passes @_ if you don't use parens. Put subs near the top to avoid sharing _all_ file scoped lexicals. This will be useful when you use strict. Third, use strict. Reasonably important: check the return value of kill. Reaping and killing are not the same, by the way. Use waitpid or wait to reap.
