> unmount failed

suggests that the user has preferred MacFusion to 

  Unmount on Sleep, Remount on Wake

> No files open

was probably not true if 

> unmount failed

but we shouldn't see this as user error. It's sometimes not easy to tell which 
files are open. For example: I recall that Microsoft Word could be 
troublesome in terms of leaving files open even after Word had quit. 

Initially I thought of using 
lsof +D
but for MacFUSE volumes, normally 

  lsof: WARNING: can't stat(.): No such file or directory

Wiith reference to the manual page for 

    Note: the authority of the user of this option limits  it 
    to searching  for  files  that the user has permission to
    examine with the system stat(2) function.

I guess, lsof might be used only when the allow_root option is specified -- but 
allow_root is not recommended.

Landon: if you're happy working in Terminal, and if you find yourself in this 
situation again, for the affected 
file system please try the command 

  umount -f 

(The command

  mount

alone will present a list of currently mounted file systems.)
