I have tried on 10.0-BETA3/amd64, too: Reading (testing the checksum of
a 3GB file) und writing (copying a 128MB file and checking it from
another machine) seems to work.

I have tried again using dd to copy -- this time for a finite amount of
data. The process is blocked (afsslp) and does not react to signals (^T
shows the load instead of the bytes transferred and ^C does nothing),
but it eventually finishes leaving the machine and afs operational. In
contrast to FreeBSD, dd does react to signals on Linux only with a
slight delay.

Anyhow, afs is usable for the light operations I usually do from
FreeBSD. Thanks!
