Thanks, yes, the buildbot master should never grow like that.

I finally discovered what was happening.  It was trying to build copies 
of Octave that included changeset 549c10384cc2, which has a stray 
"keyboard" in a test.  So it was apparently filling up some internal 
buffers for the results of the tests with "keyboard> " repeated endlessly.

I didn't need the profiler, but it's good to know that it exists in case 
we do need something like that in the future.

So, I reduced the size of the droplet again (no need to double the cost 
if we don't need it) and I'm attempting to make it skip that revision.
