It appears that setting 
debug.bootverbose=1 
suppresses the otherwise-persistent
Khelp module "ertt" can't unload until its refcount drops from 1 to 0.
message during shutdown. No new output either, apart from the swap
removal notice.

So far, the few shutdown -r experiments tried have not gotten stuck,
even after an OS build/install cycle.

Thanks for all your help!
