I assume there is sufficient SHM available for the worst case usage?

If so then in jack_port_get_buffer it should be possible to first check
if this is necessary then memcpy into the b uffer that would have been
used in the unoptimised case and return the pointer to that block
instead of the original one?

No client changes required and deferred jack_port_get_buffer works as
intended. 

I am guessing slightly here as the internal architecture of jack is
something I understand in outline but not in detail.
