The best solution is probably to fix the CGI itself ;-)

The nice() function is in the POSIX module.  You use it like this:

use POSIX ();
POSIX::nice(19);

See "man POSIX" and "man 2 nice" for details.

But seriously: Fix the script instead.  If it's stuck in a loop, fix
the loop.  If your system load is too high because of too many CGIs
beeing executed, have a look at mod_perl.
