Unless something major has changed, the automatic di generator is pretty 
pointless. It strips almost nothing. There was a pull request which changed 
that, but I don't remember what happened with that. I don't remember it being 
merged (though it might have been). However, in preparation for that, I 
believe that the makefile was changed to just copy and rename the files instead 
of using the generator (since we really don't want all of those files stripped 
normally since it kills CTFE). Either way, we don't want thread.di being 
treated like all of the other .di files in druntime.

I remember getting the impression that thread.di required better control over 
what was and wasn't in there than the generator was likely to provide even 
with stripping stuff, but I'd have to go dig through archives for discussions 
on that. So, if the generator was updated to actually strip most stuff, then it 
might work, or it might not.

Martin is likely to know more, since he's the one who made the change in the 
first place.
