That's my experience with Ada83 programs with large numbers of tasks as well. You end up
having to create tons of extra tasks and task types to handle inter-task synchornization
issues. Such issues can typically be handled with protected types now. So he may have some
real success in reducing the amount of tasks just by converting some of them to protected
objects.
