More detail on this.  Seeing programs crash after restart on an i386 KVM
guest with Fedora 12 userspace, e.g.

bash-simple.sh[3627] general protection ip:b76d8197 sp:bfe73904 error:0
in libc-2.11.1.so[b760e000+16f000]

kernel: ckpt-v21-rc1 (v2.6.33-108-g9f4401c)

user-cr: ckpt-v20 ( 70a5c7630ce8dd933e60174aba6dc5cb08ea4b41) with
CHECKPOINT_NONETNS flag added to checkpoint calls

cr_tests: master (7bd883e17f25d36d66f9b550194c445df2f63e7e) with
CHECKPOINT_NONETNS flag added to simple/ckpt.c.

The "simple" (self-checkpoint) testcase restarts successfully without
crashing.  Everything else seems to get crashes as above.  As far as I
can tell the memory map is restored correctly and from the kernel's POV
the restart is successful.

FWIW, I don't see these crashes on another KVM guest where the only
difference is that it is x86_64.
