Description of problem:

Running any X11 application ends with:

[zaitcev@lembas ~]$ xterm
Xlib: connection to ":0.0" refused by server
Xlib: Maximum number of clients reached
xterm Xt error: Can't open display: :0.0

Apparently, all those sockets are tied by Firefox. I'll attach output of lsof.

Additional info:

I have Flash 9 beta, maybe that's it... I'll kill it and retest.
