xpra_signal_listener - fake process utility used by xpra to receive signals

xpra_signal_listener

xpra_signal_listener is used by xpra to ensure that all the NET_WM_PID of remote windows will have a valid corresponding NET_WM_PID on the client windows.

This process is just a placeholder that waits for a signal to exit. The exit code is the value of the signal plus 128. ie: on SIGINT the exit code is 130.
