[fdo-internals] Counting rows in managed IFeatureReader

[Jason Birch]

So, there is no safe way of getting the count of features that are going
to be returned?

Even with transactional support, you don't have a guarantee that two
selects will return the same results unless the server supports a
snapshot or serializable type of transaction isolation level, which is
not usually default. Typical isolation levels are read-committed. But,
this would be the same case regardless of whether you did a select
aggregates and then a select versus running a select twice.
