I can see that it's no problem in the gen_server implementation.

But I can't see anything in the documentation which prohibits a future
gen_server from breaking the reply-before-return.

So the paranoid and prudent might prefer to avoid calling reply()
first, unless you know that a large Ericsson project contains code
like that, in which case you can relax. ;-)
