	Different problem. The "display lock" stuff is caused by the
SunView compatibility support in the server. SunView has the concept
of a display lock during which only one process can draw into the
screen's framebuffer. Processes are supposed to get the display lock
and then draw something and then release it. Occasionally the server
holds the lock too long and the kernel emits the above warning message.
This isn't a big deal, but it's annoying to get the messages. There
is a way to patch the kernel to increase the default display lock timeout
but I don't know off hand what it is.
