I disagree.  It is a consequence of the fact that the actual resizing
is performed by the window manager, and that Emacs must wait for the
window-system response event to perform the resize correctly.  Lisp
programs that perform several such operations in a row must inject
short wait periods to allow for the processing of the window-system
events.  That's what Martin meant by saying that using sit-for solves
the problems.

So this isn't a bug, but a limitation caused by the way Emacs's
interaction with the GUI systems is designed.  If by "bug" you mean
that design, then it is pointless to keep such "bugs" open, since no
one is working on redesigning that aspect of Emacs, nor intends to do
so any time soon.
