--- Comment #3 from David Cook <dcook at prosentient.com.au> ---
All we need to do is the following at the top of updatedatabase.pl:

my $original_version = C4::Context->preference("Version");
my $code_version = $Koha::VERSION;

if ( $original_version >= TransformToNum($code_version){
    exit 0;
}

If the code version is the same or higher than the current database version,
then there cannot possibly be any database updates to run, and we should exit
immediately, rather than consuming 100% CPU for way too long by doing 23,000
lines of updates.

This is a short-term solution as overhauling the database update system is the
long-term solution.
