This is mostly a duplicate of bug 226943, but for customer 532 I have a
%ram% IODevice that allows files to be created as 'foreign' using C calls
on a block by block basis and used as input for ANY PDL that performs the
IODevice access (as with sfopen, sfread, ... defined in base/strmio.h) or
by the PS 'file' operator which parses the %___% IODevice prefix.

As long as the stream returned to the PS interpreter from the "file"
is "seekable" (returns 'true' from s_can_seek) then the PDF interpreter will
not create a ResuableStreamDecode filter.

This approach is better than the %memory% device I provided as a quick
and dirty for a customer that required that the data be contiguous.
