Are there any plans to fix the GC so that it actually _works_ (with
nontrivial buffer sizes)?

The GC actually works fairly well with normal buffer sizes for your example. It
even supports large *buffers* extremely well. But, your example isn't about
buffers. It's about array building. No language supports appending to a vector
at scale well; whether D's runtime crashing (i.e. fail early, fail often) vs
other languages' silent, massive performance and/or memory hit is better or
worse is debatable.
The right solution is to use a better algorithm: in D, you're supposed to use
appender. Now, the current appender does have its own issues,
(http://d.puremagic.com/issues/show_bug.cgi?id=5813), but hopefully I'll finish
putting together the pull request sometime next week.
