With a slightly older kernel it still hangs, but in a different
place, namely a mkstemp/open call. This time I noticed that top
shows it is stuck in a tsleep on "lfsresbuf", which would make
sense since the source and all the working directories live on an
LFS. I'll try the new kernel again and see if that is stuck on the
same tsleep.
