+// History (may be apocryphal)
+//
+// Around V2, an HTTP inventory download mechanism was added
+// along with inventory LINK items referencing other inventory
+// items. As part of this, at login, the entire inventory
+// structure is downloaded 'in the background' using the
+// backgroundFetch()/bulkFetch() methods. The UDP path can
+// still be used and is found in the 'DEPRECATED OLD CODE'
+// section.
+//
+// The old UDP path implemented a throttle that adapted
+// itself during running. The mechanism survived info HTTP
+// somewhat but was pinned to poll the HTTP plumbing at
+// 0.5S intervals. The reasons for this particular value
+// have been lost. It's possible to switch between UDP
+// and HTTP while this is happening but there may be
+// surprises in what happens in that case.
+//
+// Conversion to llcorehttp reduced the number of connections
+// used but batches more data and queues more requests (but
+// doesn't due pipelining due to libcurl restrictions). The
+// poll interval above was re-examined and reduced to get
+// inventory into the viewer more quickly.
+//
+// Possible future work:
+//
+// * Don't download the entire heirarchy in one go (which
+// might have been how V1 worked). Implications for
+// links (which may not have a valid target) and search
+// which would then be missing data.
+//
+// * Review the download rate throttling. Slow then fast?
+// Detect bandwidth usage and speed up when it drops?
+//
+// * An error on a fetch could be due to one item in the batch.
+// If the batch were broken up, perhaps more of the inventory
+// would download. (Handwave here, not certain this is an
+// issue in practice.)
+//
+// * Conversion to AISv3.
