Didn't get you... Are you talking about the following change in the
total_refresh()?

titlebar(currmenu == MFINDINHELP ? title : NULL);

I previously avoided it as it makes a variable global (variable title
namely) and the update/s in topwin is visible (you could see title in
topwin change in quick successions).

I /initially/ thought rewrapping and recopying the help text and
closing and reopening the buffer would be lengthy enough to introduce
a lag. So I was wondering about the possible options.

Is having top 2 help functions, one for each with and without
multibuffer disabled, is bad option?

Oh...  It is much better this way. I should have considered this
common sense: don't repeat the code. But I, unfortunately, miss these
good practices despite of the fact that I know them.  :|

By the way, what is the effect is achieved by this change? Is it only
an optimization -- avoiding considerations of locking for help text? I
couldn't figure.

-       if (has_valid_path(realname)) {
+       if (currmenu != MHELP && has_valid_path(realname)) {
