It's called GC phobia, a knee-jerk reaction malady common among C/C++ programmers
I'd like to use D in hard realtime apps (gaming can be thought as one of them, but I mostly mean realtime dynamic multimedia and digital signal processing).
So, GC in such applications commonly supposed unacceptable. In contrast, I can find some PhD theses speaking about realtime GC, prioritized message passing and maybe RDMA-based clustering.
Unfortunately, I have no hope that D lang is popular enough that somebody in the topic can rewrite its runtime and gc to be usable in more or less hard RT apps.
