Not.  At.  All.  Let's say that I get a copy of some TGPPL code.  I
immediately release it under the OSL.  What happens to that code
release in a year?  I can think of two possibilities:

  1) The OSL remains in force, in which case, the TGPPL is really the
GPPL; its transitive nature being completely lost.  Note that I could
also do this on day 364 of my 12 months.

  2) The OSL expires, except that the OSL says it doesn't expire as
long as the copyright remains in force.  That means that the code was
never *really* licensed under the OSL, at which point the judge would
throw up his hands and say "You're all completely insane; get out of
my courtroom."

Either way, very bad things happen.
