I've never seen this happen. What do you get when this is happening
and you do "xlsclients | sort | uniq -c" ? I currently have 64 X
clients running here. Most KDE things show up as 2 or 3 X clients.
plasma-desktop shows up as 20. firefox shows up as 1.

It probably seemed like a reasonable assumption back when the X11
protocol was designed that an X client would only make 1 connection to
the server, and that having 256 or 512 X clients at once was enough. I
don't have the Xorg source here so can't find where this is set, either.

What did you mean by "flocks"? If Chrome creates a separate X client
for every browser tab, that'd probably cause stupidity, but I could see
it doing that. (Having fewer than 30 tabs open at any given time would
fix that if it were the case.)

Obviously not if you found some other people complaining on a search
engine. First thing to do is figure out which program is causing the
stupidity. I was surprised to see 20 plasma-desktop clients here,
because plasma applets are useless and I didn't think I had any of them
running at all.
