The only reproducer that I have at the moment is the autopkgtest command
mentioned in the bug, that is a bit convoluted, I'll try to see if I can
better isolate the problem and find a simpler reproducer, but I'll also
be travelling next week to a Canonical event.

Note that the netfslib has some tracepoints that might help debug it.
