IMO the gcProxy approach is so limited (no multi-threading, no sharing of other
resources) that we should rather remove that section or add a large flashing
warning at the top. We need something like
https://dconf.org/2016/talks/thaut.html to support sharing the runtime across
DLLs.

If someone actually uses the gcProxy, a simple fix should be to disable
parallel marking by adding this line

extern (C) __gshared string[] rt_options = ["gcopt=parallel:0"];
