I did add the uid - havent done the gid as part of the mount(...) method.

remove() tended to leave 0 length fiiles.  unlink() didn't touch the file
length when it failed.

I think I have it going, I try umount2(xyz, 0); several times (if it fails,
with a sleep),
then do a umount2(xyz,FORCE); at last.
The work cases of lingering files were if I just did a forced umount2.

I also added the uid as part of the 'data' parm of the mount, which may also
have helped.
