// Type A) Parser blocking script loads will have an mContentPolicyType
//         indicating a script load and a nsIClassOfService::Leader class of service.
// Type B) I couldn’t find a class flag that corresponds to synchronous loads
//         that block the load event, but I think a simple way to determine
//         which ones they are is to examine whether the channel belongs to a
//         load group and do not have a LOAD_BACKGROUND load flag.
//         If that condition holds, then it is blocking the load event of some document.
// Type C) I think a simple way to find channels that don’t block document loads
//         (e.g. XHR and fetch) is to look for those which are in a load group
//         and have a LOAD_BACKGROUND load flag.
