Just a note that the 0.8.1 release available in maverick gives me about a 50-second save for a 512M memory image (producing 100M outfile). The patch listed above and suspected of speeding the saves is not in 0.8.1. When I hand-apply just that patch, saves take about 8 seconds, but restore fails. Presumably taking the whole of latest git (or 0.8.2 whenever it is released) will result in both working and fast save/restore.
