Yes.


Maybe I could avoid the word "chained" and replace that paragraph with
something like:
"Commands can be submited one after an other with the same connection.
(e.g. the result from the "add-fd" command need to be use in a follow-up
command before disconnecting from QMP). A libxl__ev_qmp can be reused
when the callback is been called in order to use the same connection."

Will do.
