I think we can cope, though. :)
Or maybe we flush out, and have a flag returned (for internal use only) about whether this is the first or subsequent time we've returned. And only re-load registers on the subsequent times. But I have this inkling that even if we never use a single continuation, the housekeeping involved may be greater than the time saved in reloading registers.
