Yes. It's just that on hurd-amd64 we don't have the choice :)

I don't think a newer upstream version would change anything: freebsd
has been working fine for a long time. Missing proper memory wiring
(e.g. perhaps the contiguous allocator) is a much more probable culprit.
Simplest would probably be to just *observe* what is happening, from the
kernel debugger, to check what rumpdisk is stuck on. Rather that making
all sorts of guesses that can take a much longer time to check.
