[Wikitech-l] What can be done with a watchlist too big to edit?

I do a lot of work on Commons, while using a setting that all pages I edit go to my watchlist. In the past I was able to control the size of my watchlist by occasionally purging it by editing raw watchlist. However when Cat-a-lot gadget become available I initially did not configure it properly and all files I edit with it also ended up on my watchlist. Pretty soon my watchlist become too big to edit. I am now at 36k pages and I definitely need to purge it.

What can be done about it? I asked few people and asked on some talk forums but nobody knew the answer. I would be OK with deleting everything.

Thanks
