Yeah, I guess that is probably it. Forgot that two different 
linkers were used... although, Not much is being linked. Visual D 
doesn't split up the two easily, I suppose I can't separate them. 
It should probably do individual profiling between the two.

Usually the build times are pretty close and I don't recall it 
being slow when I first started building, and my code hasn't 
changed much... But I did modify a few options such as debug 
diagnostics and such as those were causing visual studio to 
freeze.

I guess I could perfmon it to see what exactly it is doing.
