savepoints in 8.3.7 or whatever...

 we have an app thats doing massive amounts of inserts, batched in
transactions, multiple concurrent connections (tuned for optimal
throughput, usually around 1 thread per cpu core plus a couple more).
occasionally a transaction gets duplicated, and that causes a constraint
violation which causes the whole transaction to abort unless we wrap
each insert in a savepoint.

my developers are asking me if there are limits as to how many
savepoints can be active, etc.   they have run into various such limits
in oracle.
