2. If the dynamic loader loads an endless stream of different modules

I think if the issue is this vs. not being able to guarantee any
once-only semantics, i consider the former necessary overhead for proper
program behavior.
Not leaking memory is an important part of proper program behaviour.
And that, given that there exists extra-program global state that
one might want to access, once-only initialization is a necessity.
In what cases? In the case of buffered I/O there's no reason (in theory)
you couldn't unload libc, do unbuffered I/O for a while, then reload libc
and start again.
