Unfortunately we can't use this option because we run into a deadlock

Our basic problem is that incoming calls can overtake each other by being
processed in different threads. The main reason for taking the client
strategy factory "Wait-on-Read Wait" (rw) was to avoid the borrowing of
other threads for incoming calls.
Because we've implemented a CSD Strategy which queues these calls for
later dispatching in an other thread it is simply the order of the
incoming calls which leads to problems in our application.
Is it possible to achieve that the ORB didn't borrows an other thread
