Sure enough. gzip -9 brings that 60MB into line with the 360K Chris
reported.

Thanks for explaining the discrepancy. This is the first time I've
worked with a live compressed filesystem. This is going to take some
getting used to. I guess the rule should be, estimate space use by
compressing to test, but never store anything compressed unless
you've got data-domain specific knowledge that can let you do better
than whatever LZ-family generic compressor is in the filesystem;
otherwise you're just thwarting the filesystem compression and
adding a wasteful extra layer. That about right?
