pulseaudio-0.9.15-10.fc11

pulseaudio-module-x11 contains /etc/xdg/autostart/pulseaudio.desktop which autostarts /usr/bin/start-pulseaudio-x11 during a desktop login.

Remote desktop sessions might set PULSE_SERVER to direct the desktop sound to another host, like:
PULSE_SERVER=tcp:172.31.100.102:4713

In this case, the pulseaudio daemon launched by the user desktop is not actually used.  This can actually cause problems for multi-user systems because these unused pulseaudio and /usr/libexec/pulse/gconf-helper processes often fail to die after logout.  Hundreds of them pile up over time bogging down system resources.

This patch seems to DTRT, preventing the unused pulseaudio daemon from launching, and no more leftover processes after user logout.
