--- Comment #2 from Andrei Alexandrescu <andrei at erdani.com> ---
A recent discussion in
https://github.com/D-Programming-Language/phobos/pull/2946 brought this to the
fore. 

We should have BUILD=release (default) and BUILD=debug for druntime, and "make
unittest" should unittest both.

Assigning to our release czar.
