Is this correct behaviour ? The Single Unix Standard for unlink() states in the 
error codes:

     The file named by the path argument cannot be unlinked
     because it is being used by the system or another process
     and the implementation considers this an error.

My reading is an open() then unlink() should fail.

When are the contents of an updated directory or the FAT sync'ed ?
