import core.memory;
GC.disable();

However, most D code - including the runtime and standard library 
- assume that a GC is present, and thus may leak memory.

The GC will not be invoked unless you allocate memory (either 
explicitly, using "new", or using D's features which do so, such 
as dynamic arrays and closures). If you do not make use of those 
features, no GC code will run.
