Good work, Matt.
I wrote the /rescue stuff and a lot of people have
reported that it breaks parallel builds, but I haven't yet
come up with anything. (In part, because I haven't yet
managed to reproduce it. <sigh>)
A couple of things look odd about this:
1) You should not be building 'rescue.mk' twice.
That could be the problem right there, if the rescue.mk
makefile is getting rebuilt (overwritten) while another
build thread is using it. The dependencies in
rescue/rescue/Makefile look right to me, but I
could be missing something.
2) I can't find the 'crunchgen_objs' or 'loop'
targets offhand. I'm doing a more extensive
find/grep search right now to see if I can figure
out where those are coming from.
Somewhere in here is the answer to this problem,
I just don't see it yet.

P.S. Could you email me the log from your build
that failed?
Could you try a lower -j value? If -j 2 fails,
for instance, that might be easier to diagnose.
Thanks for all your help.
