814	RTS always grabs 256Mb on startup	simonmar		"Two bugs really: 

 * on Windows, the RTS always reserves 256Mb of memory on startup.
 * to use more than 256Mb, you have to use +RTS -M

I think this is a hangover from the days before HEAP_ALLOCED was implemented with an array lookup; I believe we could now implement MBlock on Windows without these drawbacks."	bug	closed	normal	6.6	Runtime System	6.4.1	fixed			Windows	Unknown/Multiple		Moderate (less than a day)
