Looking at 1bf70e6c3a53 again I wonder if we should revert it, sort of,
and add its logic back as a new function called poll_nft?

The thing is C YNL has check_ntf too - ynl_ntf_check() and it has the
old semantics. Would be nice for similarly named functions to behave
the same across languages.

WDYT Donald? Sorry for not thinking about this earlier.

Xiao, feel free to submit this separately from the series.
