Does Writeln even use the GC to display a single string?
Not if all goes well, but a good chunk of the library is loaded
to handle various situations. It might call a GC function if
there's no stdout.
Take a look at this:

There's a lot of functions loaded from the library for cases that
are very rare... like error writing out hello world is actually
detected and thrown as an exception. There's also things in for
module initializers and class factories that you don't use, but
it is intertwined enough that the linker isn't able to optimize
it out.
In a larger program, you'd probably actually use this stuff so
the cost would diminish, but for a small program it is a bit
tangled at this level.
