FWIW, I tried it on a 64 bit machine running Fedora (the build
machine), and the numbers are different -- takes about 6 minutes real
time and 7s user time (and this is not a slow machine), and memory use
was at 103-104mb.  But the memory was *very* stable there.  I tried it
both with 4.2.3 and the newest nightly build (which was 6s slower
overall, with 0.5s more in user time).
