You forgot to make the flag static for AtomicSingleton.
Ah. It was copied verbatim from reddit, I guess we both missed
it.
Yeah, with D's verbosity in this cases it's easy to miss.
Here's mine:
$ dmd -release -inline -O -noboundscheck -unittest -run
singleton.d
Test time for LockSingleton: 577.5 msecs.
Test time for SyncSingleton: 9.25 msecs.
Test time for AtomicSingleton: 159.75 msecs.
Maybe ldc's optimizer is just much better at this?
It is :)

In either case how come the atomic version is slower?
It may not be universally true, as Dmitry mentioned. On some
platforms, TLS could be slow but atomics fast. I'm suspecting
that on Windows TLS could be slower, actually.
