The kernel suspends programs and copies them to swap? I believe it does
not suspend them. Is there something I don't know about?

The kernel will move under certain circumstances to aggressively copy data
to swap, but I believe the programs are still running and if they access
pages the data can be copied back out of swap into memory.
