Comment (by warner):

 Hm. I only see one place in the code where `2**64` makes an appearance,
 which is in the storage server, when `fileutil_get_available_space()`
 returns None. I've seen this return None on some virtual servers (maybe
 with network-based disks?), when the `os.statvfs` call fails: #2290 was
 for this happening on the Travis-CI build machines.

 If that function returns None, then the server will indeed report that
 moon-sized available space.

 The server in question was my own, and when I ran `get_available_space()`
 just now, it return about 10GB as expected. I did restart the server once
 or twice while we were setting up the demo (changing the webapi port's
 interface= so I could see it remotely). Maybe the statvfs failed the first
 time it came up, but succeeded the second time?
