Apparently that specific problem wasn't with the active pages of either
the Xterm process or the Xserver process -- but rather with Xshm pages.

(personally I've never seen an xterm process in this state, even though
most of mine have enormous scroll-back buffers -- I've only seen it
happen with really enormous programs that require a huge RSS to
function, and I've only ever seen it in truly pathological and quite
rare scenarios, with otherwise properly sized systems that is, and UBC
has, if anything in my experience, only made things better and never
worse, though UVM certainly deserves some credit here too)
