Haven't tried mfs. But r226617 was MFC'd only yesterday, so I'd guess it
would not include it.

RC2 crashes for me, i.e. does not fix the issue (but otoh does not
include r226617 either).

The build finished eventually. It was just a one-time crash but I
thought might as well report it here. Seems like it is entirely Vbox's
fault though: my update to 4.1.6 was prob not a good idea. There are
other things that are wonky... (it just trashed the disk image is used
to build a new release).
