Yes, the system will need more RAM/Swap when using a high -j value.

My benchmarks some time ago showed that 64-bit binaries were about 15%
larger than 32-bit binaries. I would think that would hold in memory too.

I'm not sure about that. My first thought is that the different
compilers may need significantly different amounts of memory. I'd just
note that "On some systems, the RAM/Swap combination needs 6 GB of
memory available." or something similar to that. It's hard to pin it
down more than that. Extra swap today doesn't really cost the user a lot.
