I agree with Keir that this is fine.  The implications are just for
performance but that's probably not important in your application.  If
that turns out not to be true then souping up your implementation can
be done later.

docs/misc/xenstore.txt has this to say on this subject:

  A caller who sends several requests may receive the replies in any
  order and must use req_id (and tx_id, if applicable) to match up
  replies to requests.  (The current implementation always replies to
  requests in the order received but this should not be relied on.)

Here a `caller' is a counterparty communicating with xenstored via the
interdomain page/event channel mechanism or locally in dom0 via a
socket - ie your driver.
