That can be discussed for years I think. ;-)

Yes, it would have been sufficient.

I did that this way by habit, and for the simple reason that next time
we will add a request, we'll get a reply that will need to be freed.
And it will require to spot every return statement in that function and
add many free() just before these statements.

And we all know we can forget to add some free().
Proof: I just fixed one of them. ;-)

(FWIW according to Arnaud's plan, bad synchronous functions like this
one will disappear anyway.)

Cheers,
