	Not OK.  Read the documentation on CreateProc.  Note that it takes
a seglist (as returned by LoadSeg), NOT a Process structure.  Anyone allocating
their own process structures will be hung by their toenails. :-)

	LoadSeg returns a BPTR.  Note that Dos is documented in the the
Bantam AmigaDos book, not the RKMs (due to an old contract).  The Autodocs
(including Dos) are available from CATS.
