Use C malloc and free.

No, an allocation can trigger a collection. D does not have a scheduled 
GC, it basically runs the GC when it can't allocate any more memory from 
it's pools before it tries to get more from the OS.

I *think* that @nogc is supposed to mean "Be able to run this without a 
GC implemented", not that no collections will run.
