The attempt to compile chromium using four USB swap partitions didn't complete, but it might have gotten far enough to be surprising. Swap use peaked around 2.4 GB, while the dual swap partition setup used around 3.5 GB of swap at maximum. The make failure happened near the 17000 counter point, when the controlling ssh connection was dropped. I _think_ that's past the point of maximum swap use, but I'll have to re-try to make sure. The log files are at http://www.zefox.net/~fbsd/rpi3/swaptests/r342204/chromium/flash_mech_sd/ in case anybody is curious.
