Not too complicated... The Modified CFB used in OpenPGP is inherently
quite pipelined if you look at the pseudocode. It could and could
probably be multithreaded quite easily: One CPU performs the encryption
to produce the CFB stream, the other performs XORs and input/output with
with the data stream. This might not provide balanced processor
utilization, but it is a way to better utilize an SMP machine.=20

Of course, this method may not be at all faster in practice, especially
if I/O is the primary bottleneck.
