We already have maildir_use_size_file; rebuilding isn't needed often.
Do we need a fast/poor quota method for cases where the size-file
cannot be used?
Other possible ways of balancing: we currently glance at the filename,
trying to pull a size encoded in it. That saves an additional per-file
stat call to get the size. But without the stat we don't have an
inode number... we can hash the filename, but that only works if
a hardlink is to a different dir but with the same name. We could
glance at the number of links, and only bother remembering >1 link
nodes - but, again, we then need to do the stat call.
