Recent /bin/sh breakage

[Andreas Gustafsson <gson%gson.org@localhost>]

Hi all,

I'm running daily automated tests of NetBSD-current which consist of
building an i386 release and then installing and booting it in a
virtual machine using Anita (misc/py-anita in pkgsrc).

As of CVS date 2009.10.30.15.09.24, the system succesfully installs,
but the installed system doesn't boot:

   root on md0a dumps on md0b
   root file system type: ffs
   warning: no /dev/console
   UVM: pid 2 (sh), uid 0 killed: out of swap
   panic: init died (signal 0, exit 11)
   fatal breakpoint trap in supervisor mode
   trap type 1 code 0 eip c019ecb4 cs 8 eflags 246 cr2 8163110 ilevel 0
   Stopped in pid 1.1 (init) at    0xc019ecb4:     popl    %ebp
   db{0}>

This breakage occurred some time between CVS dates 2009.10.29.14.49.40
and 2009.10.30.15.09.24, but narrowing it down closer than that is
difficult because in most of the intervening period, -current didn't
even build.
