Hello,
Three things...
1) Josh, the main developer for checkpoint/restart, has been away for
a few weeks
and has just returned.  I suspect he will get unburied from e-mail in
another day or two.

2) The 1.4 (and 1.3) branch is very much under rapid development, and
there will be times
when basic functionality will just break for a day or so.  If you run
into a problem, please try
to be more specific about what version (include the r#) that you tried.

3) The checkpoint/restart functionality currently only supports a
subset of the network
transports.  I think all that you should expect to work right now is
TCP and shared memory.
Josh is working on other transports, but those are very much a "work
in progress".
