I'm in favor of applying the _FAST_READ part of the patch (after you change it
to _GST_FAST_READ()), since I'm pretty confident of its usefulness and speed.

On the write side, mixing sizes of adjacent writes really slows down cpu write
combining on current microarchitectures, so I'm uncertain whether _FAST_WRITE()
would be faster when mixed with byte writing.  I could be convinced by a single
data point, however.
