The tail containing the final PFN table, VCPU contexts and shared_info_page is buffered, then the read loop is restarted. After the first pass, incoming pages are buffered until the next tail is read, completing a new consistent checkpoint. At this point, the memory changes are applied and the loop begins again. When the fd read fails, the tail buffer is processed. Signed-off-by: Brendan Cully <brendan@cs.ubc.ca>
