</span>Huh. I wonder if that should be fixed in code instead?<br>
Could anything outside libwayland-client care about when the hidden<br>
internal display queue dispatches?

Dispatching the display queue cannot create requests one might need to<br>

Hmm, but the correction you did to the doc is good, accurate to the<br>
code AFAIK, and not doing a non-obvious change in the code is probably<br>
for the better. Yeah, nevermind, I think. :-)<br>
