This starts Chromium totally fresh and indeed "solves" the issue:
$ xwininfo -root -children|wc -l
255

I have to wonder whether this is a consequences of Chromium
"Shift-Ctrl-T" feature that enables to reopen <what number> of
previously closed tabs. If it's somehow keeping track of /all/ the
tabs I've ever opened during my session, and "somehow" correlates this
to a number of X window instances, then it would make sense, though it
would be a major design flaw.
