i think this patch misunderstands the situation. the patch
claims that some code is wrong because sleep in a kproc might
get interrupted.

the crux of the matter is when sleep might be interrupted. sleep
is interrupted iff process received a note.
since kprocs don't get notes (it's an error to write to the note file),
sleep in a kproc can't get interrupted. this code will never fire.
