Ah, I forgot to talk about the general stability of the port.

The main concern is that it looks like swapping doesn't work well with
rumpdisk, perhaps something like rumpdisk or pci-arbiter not managing
to wire themselves completely, and thus getting a hang if any part
gets swapped out. This means I had to disable swap entirely to keep
the box a bit more stable. But then when building packages that are a
bit demanding in memory we end up with lack of memory and other stuck
conditions (the buildd box has only 3G memory). Merely e.g. unpacking
texlive-latex-extra can lock the box. For some packages that we really
want, I built them by hand on a vm on a server that has a lot of memory.

Also, it looks like we are encountering deadlocks in ext2fs/libdiskfs
that we had not seen (most probably only by sheer luck) on i386.

All in all, I have to reboot the buildd box several times a day
(while the i386 buildds can compile packages for several weeks before
encountering hangs).
