It seems difficult to bound the time taken by that initial scan, at
least for certain queries.
This doesn't fit well with the observation that certain filesystem
clients (most notably certain versions of NFS) have hard deadlines (due
to a ticking timer on the client) on how long primitive filesystem
operations can take before the client thinks the filesystem is broken.
