You might want to try the .nrv2brom variant as well.  I probably
should just totally switch so we don't have an excess of compressors,
something else to do before 5.2.

O.k.  So the 3c509 is done. Cool.

all it does is give an increasingly longer timeout every time it
is hit, so it shouldn't be a correctness problem.
