#define MAX_PLUGINOUTPUT_LENGTH      (332 + (16 * (64 / __WORDSIZE)))

Since pointers and long's are always words (in the asm sense), it will 
always use an output buffer of maximum size, while keeping it below the 
POSIX-required minimum atomic write(2) size.

Or better yet, use a tcp-socket listening on either 127.0.0.1 (if you 
intend to port it to Windows some day) or a udp unix socket (if you 
don't. udp is a lot simpler since you don't have the disturbing problems 
of multiplexing connectivity) for feeding results back in. That way you 
can set the receive-buffers to 256K and never worry about it again. It 
would also scale a lot better. In fact, I think I'll start hacking on 
that later today.
