# strictpagecheck and adjustwidth - buglet in memoir and related questions

My documents have frequent material that requires checking whether I am verso or recto (either marginals or material where I am adjusting the margin width via adjustwidth). Generally I have not had to use strict page checking (memoir) but occasionally I do.

Memoir has a command \strictpagecheck which turns strict checking on. It is also supposed to have a command \lazypagecheck which turns strictness off. See below mwe. So questions:

a) Memoir does not in fact appear to have the promised \lazypagecheck (try uncommenting line in mwe) - is this a bug or am I doing something silly

b) How do I turn strictness off?

c) Is there any merit in turning it on and off in the selective bits causing trouble? Clearly it requires 2 passes, but my document requires multiple passes anyway. So what additional hit in terms of memory useage and time?

d) and as a tangential question, if centering via adjustwith* spans multiple pages it clearly does not work (try increasing lipsum to [1-10]). How do others deal with adjustwith* which will or might span more than a page. Any clever methods to center the textblock over several consecutive pages?

\documentclass[12pt,twoside,a4paper]{memoir}
\usepackage{lipsum}
\begin{document}
\calccentering{\unitlength}
\strictpagecheck
\lipsum[1]
%\lazypagecheck
\end{document}


(a) Typo in the manual, it is really called \easypagecheck (will fix the manual)
(b) \easypagecheck
(d) There are other threads around as to how one could handle adjustwidth spanning page breaks. As for memoir adjustwidth was never intended to be used for anything other than sniplets that would fix on a single page. What exactly are you using it for that require several pages?
