   Description: There is no way to remove a FIFO or PIPE created in the
                psuedo filesystem.  Once created, they persist indefinitely
-               and cannot be unlinked.

+               and cannot be unlinked.  This is actually a more generic
+               issue:  unlink does not work for anything in the psuedo-
+               filesystem.
+  Status:      Open, but partially resolved: pipe buffer is at least freed
