You can exclude that directory, however if you include it the script will keep working until one of three things happen:
1. You run out of disk space and it stops.
2. It times out. php won't time out but the web server (apache, lighttpd) might. I believe apache is set to 300 seconds (5 mins) by default so I hope it's a fast disk in that server.
3. Some other problem such as the host rebooting the server.
