Jeffrey,

Sorry about the delay in replying.  I've been really busy lately.

I believe there is always an attrib file created.  It would be
a minor optimization not to write empty attrib files.

Yes.  If there is no attrib file the necessary meta-data is created
by reading the directory.  If it is empty then the effect will be the
same as an empty attrib file.

No other files should be in the attrib file: files that are there
plus type=10 (delete).

After your file system corruption problem was fixed?

Yes.  But this shouldn't happen.

Yes, they are pooled in the same way as regular files.
