The reason the answer is "not necessarily" is because it is highly
likely that a zero-filled page may have been pre-filtered by one of the
other DL_EXCLUDE_xxx bits, and therefore it would have been excluded
prior to the subsequent DL_EXCLUDE_ZERO check.
And again, the --zero_excluded flag allows a crash user to prevent
a command from failing due to an excluded page. But the result of
doing so is also completely unpredictable, so it should only be used
with care and understanding...
Thanks. I suspect the page is free and will dig into the memory
allocator.
