In recent IB versions, read committed transactions don't block GC and this
is good. But they don't track blob references as this is not as good. So
there may be a moment of time when you have a blob id to fetch the blob
contents, but the blob is already garbage collected. As a result, you will
either get a runtime error or a wrong blob content, depending on whether
this blob id has been reused or not. At least this is what I remember from
the previous discussion.
