Debugging NULL pointers is significantly easier than random memory.
Plus, if new fields (such as pointer barriers) are added they may just be
properly initialised.

We really need symbols, compat, keynames, vmods and types for a sensible keymap.
Try this in your xorg.conf.d snippets for all keyboards:
Option "XkbLayout" "us"
Option "XkbVariant" "nodeadkeys"
us(nodeadkeys) doesn't exist so xkbcomp provides everything but the symbols
map. We say we want everything but don't _need_ anything, the server happily
gives us a keymap with every key mapped to NoSymbol. This in turn isn't what
we want after all.
So instead, require symbols, compat, keynames, vmods and types from the
keymap and if that fails, load the default keymap instead. If that fails
too, all bets are off.

The EDID processing regards physical dimensions of 0mm x 0mm as
invalid. Previously the old values for height and width would be
preserved if none of the physical dimension specifications in the new
EDID were considered valid.
This will come up in particular if first a monitor is connected to an
output, and then a projector is connected. Since projectors generally
report physical dimensions of 0mm x 0mm, this would result in the
projector claiming to have the physical dimensions of the monitor.

- Apps like xterm can trigger a lot of fallback rendering.
- This can lead to (annoyingly) high latencies, because you
have to wait for the block handler.
- You need a driver that doesn't directly access the front
buffer to trigger this (NV50+ nouveau for example).
- Repeatingly doing dmesg on an xterm with a bitmap font
will reveal that you never see part of the text.
- I have recieved at least one complaint in the past of slow
terminal performance, which was related to core font
rendering.
- This does sacrifice some throughput, roughly 33% slower.

"delete pervasively use of DISPATCH_PROC" (2010-09-28), which is a bit worrying as

expectID will always be true, and we'll no longer catch XID collisions
