Review Comment:
@anchao I disagree.
I think it is greatly beneficial to have the ability to fine tune each
protocol independently.
For example, a system may have a finite number of expected UDP connections,
so dyn. alloc. is disabled for safety.
On the other hand, TCP may be unpredictable, so more connections may be
needed.
