DoReadTCP automatically disposes the old read buffer handle before doing the read, and then locks the new read buffer handle before returning. This removes the need for most explicit locking/unlocking of the handle. A macro is provided to dispose of the handle earlier (useful in a few cases where it may be big, and another read isn't immediately performed). Also, set displayInProgress to FALSE in NextRect, rather than in code for each encoding.
