And I'm half-way done with the 64 bit mmap sliding window. You,
Junio and I are all hacking on the same tiny bit of core code for
different reasons. :-)
Right now I'm struggling with merging my 32 bit sliding window onto
Junio's 64 bit index in pu. The merge is almost done, but so is
my dinner. So dinner first. I don't think I'm going to get the
sliding window code out tonight.
