I had hoped to work on this this week, along with moving the syscall
gateway page out of user space (for native linux apps).  However, I have
not been able to get my C3000 to boot.  Every time I fix a problem, I find
another (right now it starts sash, but I don't get a shell prompt).
Perhaps if I can find an A180 today I can use that for a while.  At this
point I'm not hopeful that I will get it done before Friday, when I leave
for a week of vacation.  So, go ahead and do it "wrong" and I'll check
it over when I get back.
