I suggested replacing the GC with a non-collecting allocator, something like the malloc/free-based stub in Druntime.  Using this, "new" will work but you'll have to call "delete" to release the memory.<

Such as flag would be very useful in cases like this. Basically, have a switch to turn D in a leaner language for OS / system development.
