Given that you went for the more complicated definition of halt() that 
calls block when event delivery is enabled, is it actually necessary to 
not compile the halt-checking routine? If event delivery is enabled in 
that function, shouldn't we return from each invocation of halt() on 
(at least) each timer interrupt? If not, I wonder why our behaviour 
there differs from native?
