[Spice-devel] changing the timing of spice client linking in migration (RHBZ #725009)

Wrong.  Now I remember what the problem was:  The qemu running on the 
target doesn't do anything but receiving data while the incoming 
migration is running.  No monitor commands, no new connections, no 
nothing.  With that pretty much any attempt to handle spice client 
migration in parallel to the vm migration isn't going to work.  I 
remember people discussing fixing that, not sure this did happen though.

cheers,
