What do you mean by PGDBG OpenMP event handling?

The OpenMP run-time support performs internal synchronization when a program enters or leaves a parallel region, and may perform synchronization within a parallel region. Because of this, PGDBG users may encounter unexpected behavior in which it appears that the program under debug blocks forever, or “hangs”. PGDBG is capable of coordinating threads into and out of OpenMP parallel regions and over OpenMP barriers and synchronization points, in order to preserve line level debugging. This facility is disabled by default, since it may slow program performance significantly. OpenMP event handling can be enabled using the ‘pgienv’ command.
