I want to mark certain files with a one-bit mark, but without
disturbing the contents of the files, their directory entries, or
requiring an external index of the files.  It seems to me that the
UF_XXX flags would be ideal for this purpose, but I am hesitant to
coerce one of the existing flags.  I notice from sys/stat.h that
11 of the bits in the user part of the flag word are officially
unused--is there some conventional way to grab one of them for this
purpose?  For example, by consulting a list of purposes for which
others have done this (maybe someone else used one for a purpose
similar to mine).
