There seems to be a huge memory leak which almost certainly accounts for
this. The Python process that runs the pyregr suite ends up with about 50GB
of memory at the end, also in the latest Py3k builds.
I have no idea where it may be, but it started to show when we merged the
generator support. That's where I noticed the instant jump in the runtime.
