Cache the work list and just restart that if less than a given age.
Allow local dir scan to be done before connection is made.
Cache the local/remote dir listing and use those if less than a given age.

Allow per-filestore defaults:
        default_fs_settings=unix{
                recurse_hard=false
                ....
        }

Handle hard-links:
In theory add 'i' to the ls flags, keep the inode number and spot
files that are really the same by having a reverse assoc lookup...
Also check file size, type, .... just in case the remote area is
actually several disks.  On recreateing the link have to check that
everything is on the same disks too.


Track down severe memory leak on processing ftp'dir_open -> get_remote_dir..
that doesn't seem to be there if local_file -> get_remote_dir..
