Swap is 3 GB, in 3 partitions of 1 GB each. A -j4 buildworld is running, it's apt to finish shortly. Running a similar test couldn't hurt if no better ideas come along. Adding swap to the microSD card would put you a step ahead of me. If you could get your hands on a Sandisk SDCZ800-064G it would be especially interesting; that's the usb stick that started this goosechase. Hopefully somebody will have better ideas.... bob prohaska
