You can switch off the GC, but then things will leak as the core 
language, druntime, and phobos all use the GC is many cases.

What I do is just avoid the functions that allocate, and rewrite 
the ones I need. I also use a modified druntime that prints 
callstacks when a GC allocation occurs, so I know if it happens 
by accident.
