So, I just tried comparing memory usage for a plot displayed via show() versus savefig() as a PNG. It would seem that saving to pngs uses more memory. Not sure why, though.

If I remember correctly, the nosttests was set up to execute in parallel
using the default Multiprocessing settings, which is to have a process
worker for each available CPU core. Perhaps this might be the crux of
the issue with so many simultaneous tests running that the amount of
memory used at the same time becomes too large. Or, am I thinking of the
doc build system?
