#8889: Wrong data read from discarded block if transaction isn't flushed

---------------------------+------------------------------
If a block has been discarded, but is still in an unflushed transaction,
old cached data will be read instead of the data on the disk.
Attached is some code to reproduce the problem (can also be seen as a more
detailed problem description), as well as my attempt at fixing it.
