You might just want to wait until tomorrow and see whether it clears
up in newer runs. I just pushed yet another fix that might be
relevant.

I think I've done about as much as I can do for tonight, though. Most
things are green now, and the ones that aren't are failing because of
stuff that is at least plausibly fixed. By morning it should be
clearer how much broken stuff is left, although that will be somewhat
complicated by at least sidewinder and seawasp needing manual
intervention to get back on track.

I apologize to everyone who has been or will be inconvenienced by all
of this. So far I've pushed 4 test case fixes, 2 bug fixes, and 1
makefile fix, which I'm pretty sure is over quota for one patch. :-(
