Savepoints in ODBC driver

while checking some performance bottlenecks I realized that the ODBC
driver is creating/deleting a savepoint for *every* command send to
the server.

Grep for SC_start_rbpoint and SC_started_rbpoint to see what I mean.
This does require 3 roundtrips to the server (instead of one) and some
additional processing time for the backend to create/delete the
savepoint every time.

What's the rational behind this? And can this be turned off somewhere?
