I assumed that one would only get more than 1 packet at a time under
heavy load, but apparently traffic is bursty enough that it even
triggers in a simple SSH session. But it rarely is over 64, so I kept it
at that.

Your patch was apparently against 1.0.26, not 1.1pre11 as you said
earlier, so I had to port it to the 1.1 branch. It's committed now, with
Michael's de-ifdeffication incorporated as well.

I also made the buffers static, as suggested by Michael. If we go the
multi-threaded way, they can be made thread-local.
