 2048M of swap are configured on a USB flash drive. Highest usage seen
 was just shy of 1000M, apparently when clang was being linked.

 Prior to the v6-v7 split j4 worked well and finished in about 18 hours, 
 j>4 didn't seem faster but did not freeze. 
 
 There seems also to be a problem with u-boot, which I (perhaps mistakenly)
 upgraded at about the same time. It began to emit streams of
 
 Timeout poll on interrupt endpoint
 
 messages. They were eliminated by simply disconnecting the USB mouse
 and keyboard (both old Dell units). I haven't yet tried another keyboard. 
 
 Thanks for reading, and any ideas!
