Piotr Sarna b4932340f4 database: add a juicy comment about serializability ...

And specifically, the amount of things we don't have implemented
to even think of that. It's mostly about tracking commit dependencies
which allow speculative reads/ignores of certain versions,
as well as making sure that in the commit phase, we validate
visibility of all versions read, as well as that our scans
took into account all data. If some version appeared after the transaction
began, and it was not taken into account during its scans, it is considered
a "phantom", and it invalidates the transaction if we strive for
serializability.
