This begs the question....could a WAKEUP type function be written for
zLinux when it is running as a guest of z/VM?

There's already code in vmur to handle unsolicited DE (it explicitly
ignores it). I'm not sure how add_uevent_var() works and how drivers
can
change the value of variable with kobject_uevent( KOBJ_CHANGE ), but
maybe
vmur could add "NEW_SPOOL_FILE" when it gets loaded, and change it's
status when the unsolicited DE arrives. (Also triggered by CP READY

command._
Udev appears to be designed to handle device status changes, not just
hotplug events.
