Thanks a bunch to both of you! That was a very interesting deep dive,
and I hope will eventually allow me to write better code.

I suppose the new-ish `define-inline' can be used instead of making
explicit calls to `inline', but either way I'll try to make sure I
preserve the effect.

My observation so far is that Gnus has lots of this sort of
micro-optimization, but that much of the slowness comes from how the
larger routines and data structures work. In fairness, we have a lot of
tools now that weren't present when Gnus was written.
