Well, in my *opinion*, if you've told the master to not "commit to"
*anything* unless it's synchronously replicated, you should already
have a synchronously replicating slave up and running.

I'm happy with the docs saying (maybe some what more politely): Before configuring your master to be completly,
wait-fully-synchronous, make sure you have a slave capable of being
synchronous ready.  Because if you've told it to never be
un-synchronous, it won't be.
