MongoCursor::dead — Checks if there are documents that have not been sent yet from the database for this cursor
The database sends responses in batches of documents, up to 4Mb of documents per response. This method checks if the database has more batches or if the result set has been exhausted.
A cursor being "dead" does not mean that
MongoCursor::hasNext() will return FALSE, it only means
that the database is done sending results to the client. The client should
continue iterating through results until
MongoCursor::hasNext() is FALSE.
