That bit is not strictly necessary; wrap it in a version check:

(in Database.php)
	function startTimer( $timeout )
	{
		global $IP;
		if( version_compare( phpversion(), "4.3.0", "gte" ) {
			# This will kill the query if it's still running after $timeout seconds.
			$tid = mysql_thread_id( $this->mConn );
			exec( "php $IP/killthread.php $timeout $tid &>/dev/null &" );
		}
	}

If you have a runaway query you'll have to wait for it to finish or kill 
it manually.

Please let us know if anything else is broken on 4.1.2; that's our 
minimum supported version and only because Debian takes twenty years to 
put out a stable release. ;) However it's not really tested very often.
