  1. Fix rare bug in read_stream.c's split IO handling. 

    The internal queue of buffers could become corrupted in a rare edge case
that failed to invalidate an entry, causing a stale buffer to be
"forwarded" to StartReadBuffers().  This is a simple fix for the
immediate problem.

A small API change might be able to remove this and related fragility
entirely, but that will have to wait a bit.

Defect in commit ed0b87c.
