Actually, there is at least one other "special" value for transaction
ids.  Zero is always
the system transaction.  If you consider that a signed long is
"retirement proof", which
we did, using the other half for something else doesn't seem so bad.
Particularly if
you cut your programming teeth in a 64Kb address space.

Maybe it's time to look at all the small integers as well.
