README.wm-session

   /proc/wm-session is used to register the process id of an
application able to free resources smoothly when the kernel decides
that memory resource have reached a critical limit. The registered
application is notified of this situation by the signal SIGUSR1.


   On full featured desktop machines it would make sense to use the
session manager for this purpose. On X window PDAs which have limited
memory resources it makes sense to let the window manager send
WM_DELETE_WINDOW message to the last recently used application.



   Requirements to uses this feature in IceWM:

  - A patched kernel, a patch for Linux 2.4.3 is available in the contrib
    file module.

  - A patched X server assiging the clients process id to each newly
    mapped window. Alternatively you can preload the preice library
    available in the contrib file module.
    
	$ export LD_PRELOAD=$PATH_TO_libpreice.so).

  - IceWM configured to have wm-session support
    (./configure --enable-wm-session ...)
