I have installed some minor fixes to uucico (the actual communications
handler for the uucp subsystem) that should speed it up substantially.
Specifically, when the other end asks whether it should send file X,
uucico goes through a real song-and-dance to check permissions.  Said
song-and-dance turns out to do a lot of redundant checking, some of
which involves scans of 10KB directories (rather expensive...), and
much of it is pointless for the normal case that account for 99% of
all traffic.  I've done some optimizing;  a night or two of decvax
traffic will give me an idea how much difference it makes.
