I think the short-term outcome was to throttle GWToolset until there is a
better fix. There is a patch pending to do that:

https://gerrit.wikimedia.org/r/#/c/132112/

I described the thinking behind the limits in this mail and the followups:
http://thread.gmane.org/gmane.org.wikimedia.glamtools/24/focus=104
tl;dr it tries to limit the GWToolset-uploaded thumbnails appearing in
Special:* at one time to 10% (5 with default settings), based on the total
upload rate in the slowest hour of an average day. That's about one image
per two minutes.

This is not live yet; Fae has apparently been running the upload with three
threads (as a side note, GWToolset should probably log this), which means
about one image per 20 sec (more precisely, three upload jobs are generated
per minute; how the job queue picks them is not controlled).

(I haven't been paying the issue much attention because I assumed that
GWToolset is inoperational anyway until the next deploy due to bug 64931.
Apparently I misunderstood how the job queue handles jobs that throw
exceptions.)
