I have no queue to flush. All i do is ignoring all event handler functions
until endBlock is called for a not-nested Block. Then i iterate recursively
through its children an call all appropriate event handlers.

For this purpose i have implemented a reference counter. Eachtime startBlock
is entered the counter is incremented. Eachtime endBlock is entered the
counter is decremented. So when the reference counter reachs 0, a not-nested
block is finished and i can process all deferred FOs. Works quite good.

Kind regards
Peter Herweg
