I just read over the proposal and I still don't see a detailed 
definition of quiescence. I know what it means when we're talking 
about checkpointing at the kernel-level(BLCR) or user-level(libckpt) 
or the application level(C3) and I can figure out what it means when 
the checkpointer works at the virtual machine monitor level, though 
that also depends on how well the VMM checkpointer supports the 
machine's network card. However, what does the spec mean? The draft 
spec doesn't provide any details and my concern is that the spec can 
never provide enough details without going into deep details of the 
network hardware and software stack.
