[Pkg-chromium-maint] Bug#618323: chromium-browser: Chromium overloads X server: "Maximum number of clients reached"

[Thibaut VARENE]

Package: chromium-browser
Version: 6.0.472.63~r59945-5+squeeze3
Severity: normal

Chromium apparently uses too many X windows, overloading the X server and
eventually making it impossible to run new applications.

Trying to start a new app fails with:

$ xwininfo
Maximum number of clients reached xwininfo:  unable to open display ':0.0'

Killing one running app allowed me to gather some data:

$ xlsclients |wc -l
37
$ xwininfo -root -children|wc -l
905
$ xwininfo -root -children|grep chromium|wc -l
626

I've made sure that the app I killed had no significant impact on these numbers.

It appears the number of open X windows is 2/3rd due to Chromium, and that it's
the cause for the subsequent impossibility to start any other X application.
(I understand the maximum number of X clients is about 255, so that's not the
issue here).

FWIW, I have only one open Chromium "window" with 15 tabs.
