Do we really want to have a bot for range preprocessing? That seems to be an
overkill.

[Mircea Trofin, 2015/08/04 20:34:46]

I don't know. I know we want to have range preprocessing enabled for linear, and
I assume we'd want to go through some fuzz testing with it. I imagined we'd do
so by having a flag and flipping it on only in certain cases - let me know how
to best stage this, though.
