Scenario: I've mounted a source tree below my own directory, and in order to
get things to compile correctly I had to modify one of the source files.
Later I got the updates to the source, so I want to delete the file that has
my changes and use the new source file.  However, if I delete my copy of the
file, the filesystem acts as if the file no longer exists, and I can't see
the original file unless I list the source directory.

How do I make that file visible again?  "cat ." shows two copies of the
filename I deleted, but ls shows nothing.  I tried "ln sourcedir/file .",
but that locked up the filesystem so my shell would no longer respond.
