The "cycle quickly enough" principle doesn't work now. It was "almost 
always works fine with very few occasional failures" an hour ago, then I

few later reboots and "make bootstrap"s.

And yes, the patch is applied and sloppy-file-time-stamps is t.

If this is too bizarre, please wait until I re-confirm this on a new 
virtual machine with a different distro.
