//
// The PendingLoadQueue is a per thread data structure which serves two purposes. First, it
// holds a "load limit" which automatically restricts the level of recursive loads to be
// one less than the current load which is preceding. This, together with the AppDomain
// LoadLock level behavior, will prevent any deadlocks from occuring due to circular
// dependencies. (Note that it is important that the loading logic understands this restriction,
// and any given level of loading must deal with the fact that any recursive loads will be partially
// unfulfilled in a specific way.)

// The second function is to queue up any unfulfilled load requests for the thread. These
// are then delivered immediately after the current load request is dealt with.
