This week I changed gdb to write out a directly-mmappable index.
Writing the index for gdb takes 2.5 seconds, and the resulting file is
19M.
I think that is more reasonable -- still not super, but livable.
I haven't written the reader side of this yet. I probably won't finish
that until sometime in January.
