Hi,
the hg repository of the spkg posted is unclean, "hg diff" gives:
{{{

(The file as-is should be the correct one, so just has to be checked in.
There is an editor-artifact file of the same name followed by a tilde in
the spkg.)
The changes themselves look pretty reasonable and OK to me, but I can't
test this on a OS X 64-bit system. I could test only whether they don't
break anything on OS X 10.4 32-bit, and I have not done this yet. However,
"1579.9 seconds" looks awesome --- on my MacIntel box with 2 GHz Core2Duo
and Mac OS X 10.4, "make -j2 test" needs over 6000 seconds.
