I was not trying to bike-shed. Just understand the problem.
If there is "good information" in the upper 32-bits then we should
display it in our logs to save developer/human time when debugging.
On linux we currently have a ProcessMessage class (might replace it in
time, but no matter). I actually do care about its size (it has a tid_t
in it) since it is passed around by value. When processing internal
events we could be generating thousands of these guys per second so
efficiency does matter -- not by much, but perhaps a little.
So these types of things are worth thinking about.
