Basically, you should do what Sean suggested - setup a ConnectionPool or
whatever it's called, that only uses one thread. That way only one command
will run at once, and it'll run in order.
Check how enterprise.adbapi interacts with the threadtask module - a
patch may be necessary in order to be able to use custom thread pools,
in which case you should patch your local install. Meanwhile I'll see if
I can add this feature so it's in 0.17.3 or whatever the next release is.
