     makes this reasonable is that st_mtime doesn't change when a file
     is unlinked, so saving st_mtime makes BFD's file cache operation
     a little more transparent for this particular usage pattern.  If we
     hadn't closed the file then we would not have lost the original
     contents, st_mtime etc.  Of course, if something is writing to an
     existing file, then this is the wrong thing to do.
