GC behavior

[Gregor Mückl]

Hi!

I'm not 100% sure if I'm in the right here, but I believe that 
the following program shouldn't have unbounded heap growth to the 
point where it runs out of memory:

module gctest;

import core.memory;
import core.thread;

void main()
{
     for(int i = 0; i < 10000; i++) {
         int[] x = new int[10000000];
         Thread.sleep(dur!"msecs"(200));
         //GC.collect(); // keeps program from failing
     }
}

If GC.collect() is called constantly, heap size stays pretty much 
constant. Tested only on Windows 10 (64 bit) with DMD 2.086.0 so 
far. I'd say that this behavior is a bug.
