The problem with intstrumentation is, that I can not recompile druntime for the MinGW GDC, as this is not possible with the binary release of MinGW GDC and I did not go thorugh the effort to setup the whole build. I'm open to suggestions though how I could profile the GC without recompiling druntime. If someone else wants to profile this, I can also provide precompiled versions of both versions.
You don't necessarily need to recompile anything with a sampling profiler like AMD Code Analyst or Very Sleepy
