In the meantime: might 252358 be the cause of a peculiarity that I 
encountered, a week or so ago, whilst using sysutils/stressdisk with a 
particular (or particular type of) USB thumb drive?

<https://github.com/ncw/stressdisk/issues/14> tl;dr whilst trying to 
test the flash device on USB at da0, there was _unexpected thrashing_ of 
the hard disk drive at ada0
