Yes, it always worried me that something I called between
splabc() and splx() might enable my interrupt while trying
to block a low priority one.

Was only when I found an spl0() call in the bowels of the
scheduler I realised this might happen.

(sort of similar to finding my ethernet tx routine being
called from within the timer interrupt.)
