In the past, CHR_EVENT_OPENED events were emitted via a pre-expired
QEMUTimer. Due to timers being processing at the tail end of each main
loop iteration, this generally meant that such events would be emitted
within the same main loop iteration, prior any client data being read
by tcp/unix socket

Public bug reported:
There are many ways to take and manage snapshots in QEMU, but one main
feature that's missing is the ability to 'loadvm' a LIVE snapshot and
have all future changes redirected to a temporary file. This would
effectively be combining the -loadvm and -snapshot switches and make
