I missed the 'sh -c' clue in your previous message.  Since sh uses
vfork, that indicates a vfork problem.  I've checked in some more
changes to deal with this.  It seems to do the right thing both with sh
-c and without.  It also should have the added benefit of doing the
right thing wrt deallocating the console appropriately since open_fhs
should now track the ctty usecount.  This was screwed up before,
apparently even before I started mucking with the tty stuff.

I sure do hate usage counting.
