There is no such thing as "THE" Ada Run Time. There are as many
implementations of an Ada Run Time as compiler/platform combinations.

Using DEC Ada (Ada83) on OpenVMS systems, we had applications
using up to 6000 tasks in one single process, with a high I/O
rate, which run quite smoothly. You can acheive this with a
robust and versatile O/S and a perfect integration of the Ada
Run Time with the underlying O/S.
