Thanks Greg -- the patch is queued for crash-7.2.2:
https://github.com/crash-utility/crash/commit/c1a8d0c968a256fc4617524aedb...
Thanks Dave. I tested the c1a8d0 github patch and the performance is good.
It might be too late to fix the commit log, but the patch contains all 4 of
my original patches, so it reduces startup+ps time 90m=>40s (rather than
45m=>40s). Not a big deal though.
