GM_xmlhttpRequests are definitely not sequential on their own, but
you're right that the network.http.* options may cause them to behave
that way. Probably the most important one is network.http.pipelining,
which, when set, will send a second HTTP request on a single
keep-alive connection before the response for the first one is
received (or something like that).
