Bob Supnik lurking? (simh PDP11 question)

On unix renaming a file just updates the directory which contains the
file. Also, from the process point of view, an opened file is a small
integer, so the process can't be notified that the opened file has
been renamed or even deleted (in that case the file will still use
blocks on the filesystem until the process dies, you just lose access
to it from outside the process).
