Test time for LockSingleton: 438 msecs.
Test time for SyncSingleton: 6.25 msecs.
Test time for AtomicSingleton: 8 msecs.
Test time for FunctionPointerSingleton: 5 msecs.

C:\dev\code\d_code>test_ldc
Test time for LockSingleton: 575.5 msecs.
Test time for SyncSingleton: 5 msecs.
Test time for AtomicSingleton: 3 msecs.
Test time for FunctionPointerSingleton: 5.25 msecs.

It seems it makes a tiny bit of difference for DMD, but LDC still
