It doesn't need to process them in parallell unless you really need to
scale the rewrites on multiple CPUs or threads making callouts to other
servers. One signle thread processing one at a time is sufficient for
your problem. The difference in your case is in how Squid uses the
helper.

Example script removing query strings from any file ending in .ext:

#!/usr/bin/perl -an
$id = $F[0];
$url = $F[1];
if ($url =~ m#\.ext\?#) {
        $url =~ s/\?.*//;
        print "$id $url\n";
        next;
}
print "$id\n";
next;

Or if you want to keep it real simple:

#!/usr/bin/perl -p
s%\.ext\?.*%.ext%;

but doesn't illustrate the principle that well, and causes a bit more
work for Squid.. (but not much)

Yes.
