This may do it -- once I told my beta users that high workloads and/or
lots of entropy use could cause hangs, they started nice'ing and
--bwlimit'ing their ssh rsyncs, and there hasn't been a hang for a few
weeks. No proof whether I was hitting another entropy bug or just
workload. (Reminder to lurkers -- I'm running 1.2 with /dev/random
major,minor set to 1,9 -- same as /dev/urandom.)

I think it should get worse if it changes at all. Your /dev/random is
1,8, right?

I feel your pain. ;-) Building a home server closet here (this is
silly valley; it'll probably even increase the house value). It's been
an 18-month project so far, 80 amp subpanel, dedicated air conditioner
in the closet, that sort of thing. Lots of conduit, wiring, structural,
attic, and drywall work. Gotta deal with the fiberglass insulation this
week -- my wife says I keep putting that part off, I keep telling her
she has no idea how itchy that stuff is... :-} The good news is, when
it's finally done it'll be able to serve as a minimal disaster recovery
site for the Xen infrastructure we're building at our shop. Woo hoo.
