I think the core file doesn't have enough information for
restoring mmap'd regions ?

While dumping a checkpoint you could save /proc/pid/maps, and
do the mmaps before restoring the rest of the state from core file.
But I'm not sure /proc/pid/maps has enough information, the "flags"
argument to mmap (thats the 4th one) doesn't seem to be shown there.
