I understand from past discussions that each Thread must have its own
Session.

TIBOTable and TIBOQuery at first instance create a default session, unless
directed other wise, all threads will use the same defailt session.

So create a trhread with a Session and then set TBOTable->IB_Session to
the thread's IBOSession, simply using the assignment TIBOTable->IB_Session =
TIBOSession
(the thread's) The owner in each thread of all IBOTables, TIBOQueries and
Transactions
must be each threads own session.
