Whatever the conditions for the X server crash, please report it (or ask
Rainier to do so) to the X.Org developers.  Between the recent deletion
of support for byte-swapping and its developers transition to only
assembling Xwayland releases, there is very little love remaining in
that organization for the rank-and-file of X users, and every reminder
of our existence counts towards restoring some of that lost dedication.
If you catch my drift.

Thanks.
