Hmmm... Either I'm missing something or Microsoft et al didn't read their
MultiFinder-friendly technical documentation very thoroughly.  The 
documentation plainly states that an application should pre-allocate space,
via the SIZE resource, enough room for the application to perform comfortably
in.  Space for sizable documents or tasks requiring additional memory (such
as pre-print imaging) can be allocated by use of any one of the new memory
manager temporary allocation procedure calls.  Call me silly but I assumed
that the new temporary memory allocation calls were written specifically
for the purpose of keeping the SIZE resource requirements reasonable.  It
would also seem to me that if applications handled this mechanism correctly,
it would obviate the need for documents to carry around their own SIZE
resource.   An application could easily open a document, determine it's size
and then allocate additional memory before reading the data into memory.
Please, if I'm incorrect, someone kindly enlighten me.
