SET currently has an "accepted behaviour" with other DBMSs, or, at least,
with Oracle, and that is to ignore the rollback ...

DROP TABLE also had an "accepted behaviour", and that was to leave it
DROPed, so "oops, I screwed up and just lost a complete table as a
result", which, IMHO, isn't particularly good ...

NOTE that I *do* think that #1 is what *should* happen, but there should
be some way of turning off that behaviour so that we don't screw up ppl
expecting "Oracles behaviour" ... I just think that implementing #1
without the 'switch' is implementing a half-measure that is gonna come
back and bite us ...
