you mean <slavebuilddir> instead of SLAVE_NAME?

Note that I dislike having stuff outside slave/<slavebuilddir>/build/ since it
tends to stay there literally for years.

What's the plan to delete stale files?

Guilty of blatant copying from below.

PeterK:  We are aiming at broad testing with the softGPU, so we shouldn't be
needing the same sort of collection as the GPU bots.  What would it take to make
these local?  Are teh defaults actually good enough?  If not, can we make them
sensible/normal?
Good point.  I agree.
