Hi Alexandre

Create an ib_connection, ib_session and ib_dataset within the thread - or
make sure only one instance of the thread can run at any time and let it use
a dedicated set of the above. Every three seconds sounds a bit scary, if
one gets delayed they will start tripping over each other and end up in a
big pile.

I use FB events to notify change and fire off the thread to refresh the
data. I only allow one background thread to run, if another event comes in,
I start a timer, ignore any other events while the timer is running and run
the thread again at the end of the timer to mop up any new changes. You
will need to use read and write memory locks to pass data between the
threads.

HTH
Regards
Paul
