 From an engineering view, I would guess fork-and-dump (on Linux and 
BSDs) is the most practical one, but I guess you probably want the code 
to stay portable C++. Then probably something with putting the result in 
a boost::interprocess::mapped_region can apply.

Otherwise, I don't quite see how IPC to another process should be 
significantly faster than writing the results to a disk buffer.

And the relative timings that Markus gives indicate that perhaps much 
can be achieved by doing a profile of the output rendering code and see 
if there are any bottlenecks that can be addressed there first.
