Agree.  BTW, after the sleep I tested C/R of a VNC server with a vi session
running inside.

I tried the above program, which is definitely more interesting, but am
having trouble with stdout after restart - restart seems to succeed, but
nothing shows up on stdout. If I redirect the output of "bc -l" to a file,
the C/R (with lxc) works fine.

I am investigating the stdout issue though.

Thanks,

Sukadev
