The issue with robustness (when talking about post-command-hook) doesn't
have much to do with heavy X calls (or performance), unless of course
those calls can hang.
The issue of robustness is that post-command-hook is not always run when
you want or need it. E.g. you may want to run your hook if point is
moved by a process-filter (or you may want to run that hook when the
user is queried via y-or-n-p), but post-command-hook is not involved
there. And OTOH post-command-hook may very well be run in the middle of
a command (if it reads from the minibuffer, for example).
These corner cases make post-command-hook brittle.
I think that for select-active-region to work the way you seem to want
it to work (i.e. auto-select as soon as the region is active and
non-empty), the "right hook" to use would be something like
a redisplay-hook (i.e. an active region is selected if/when it gets
displayed). I would welcome such a hook, BTW, especially if it gets run
*before* redisplay. Could be useful for reveal-mode and maybe also to
move the region-face handling to Elisp.
