Review comment:
well, the concerns about putting excess work on the driver are certainly not
as important on the SHS. Performance still matters, of course, but there maybe
more options to speed things up (eg., running multiple processes to create
snapshots in parallel). And we're still concerned about having a small
snapshot file (if its too big, it won't be fast to load, of course). We dont'
know for sure what that file size will be till we actually build it ... but my
gut is that we can store all the required info in the snapshot file and keep
things reasonably sized.
