That's really the default. The GC in D runs if and only if you do 
a GC allocation and there isn't enough memory in its existing 
pool. Then it tries to do a collection to make room (and if that 
fails, it asks the operating system for more memory to grow its 
arena, and if that fails, it throws OutOfMemoryError).

If you call GC.disable, it just sets a flag to skip the try 
collection step.


But, in any case, the GC doesn't sit around in the background 
constantly running at random times. It only runs when you call on 
it to allocate.
