6f3b0c05c2 Improve comments for surctionproof init+alloc/destroy funcs 
The comments with 'XXX' was intended to indicate that the listed
concerns was subject to review and change, but the code with these
comments was merged straight away. This commit replaces comments
with more complete text describing the issues.

This also signifies that the commit that this code was introduced in is
not anymore 'work in progress'.
