D's garbage collection is global, and either off or on (and a lot of D libraries leak memory like crazy if it is off, so in practice it has to be on most of the time)
Rust's per task GC seems like it should allow more flexibility, and I'm hoping it would be usable in the High Frequency Trading arena, for example.

That makes it sound like you can't use GC and manual memory management together; you can - std.container uses manual memory management internally for max efficiency.
