Let's try this again :) You were most of the way there the first time,
and the shell script thing I suggested is unnecessary.
system("command >/dev/null &"); # works for me
Specifically:
sleep.pl:
#!/usr/bin/perl
$|++;
print STDERR time." start of sleep\n";
sleep(5);
print STDERR time." end of sleep\n";
sleep.cgi:
#!/usr/bin/perl
system('/path/to/sleep.pl >/dev/null &');
print "Content-type: text/html\n\n";
print "<h1>done printing</h1>".time;
