Re: oskit-mach: vm_map_copyout crash

[Roland McGrath]

It seems likely that this crash is due to improper reentrance.  I am
suspicious of your other patch, because the situation it disables the check
for is just the kind of situation I would suspect in this kind of lossage.

I am not going to be comfortable with any tweak-around-the-edges approach
to tracking this down.  We really need to make sure that the oskit
interactions are happening the way they should.  It was pretty damn hairy
figuring that stuff out the first time, and I don't think we'll get it
right this time without just as much hard work and true grokage of the oskit.
Since I am not in a position to dive into it myself (no test machine),
I don't know off hand what help I can offer.
