I don't want to file a bug with this, because it seems dependent on
installation location, would possibly not be reproducible.
I can't reproduce this with DMD from DVM (compiler is installed in the
user home directory).
I have lots of version laying around and they all worked fine on the
posted code.
But maybe a clue here...

I wonder if dmd -v will show where its picking up stuff.
Thank you. It is something I missed. Lo and behold:
dmd -v mod1.d:
...
import core.thread (/usr/share/dmd/src/druntime/import/core/thread.di)
...
~/Downloads/dmd2/osx/bin/dmd -v mod1.d:
...
import core.thread
(/Users/steves/Downloads/dmd2/osx/bin/../../src/druntime/import/core/thread.d)
...
Hm... thread.di vs thread.d (and I didn't notice before because all the
other imports were .d, I just glanced over that detail).
And so, let's see here:
ls -l /usr/share/dmd/src/druntime/import/core/thread.*
-rw-rw-r-- 1 steves staff 157781 Mar 24 10:44 thread.d
-rw-rw-r--+ 1 steves staff 31382 Feb 24 2014 thread.di
Hey, looky there :)
So, looking at time machine (love that feature), I found that when I
installed 2.066, back in October, we had switched to using thread.d
instead of thread.di. But the installer did not erase the old thread.di.
BTW, found this: https://github.com/D-Programming-Language/druntime/pull/865
So I think the issue here is that the pkg installer on OSX does not
clean up the target directory if it already exists (or at least
purposely remove thread.di). Will look into fixing that. At least now,
it works properly, thanks (did a rm -rf /usr/share/dmd and reinstall).
