11a0eb679c Fix race condition
The first timer interrupt might occur before the heap is initialized. With lazy_static, this causes an allocation failure since the VecDeque is allocated when it's accessed the first time. This commit fixes this by only initializing VecDeque in `add_thread`.

75d826bf69 Add a test that memory is reused with a long lived allocation
This test fails for the bump allocator because it can only free the complete heap at once, which is prevented by the single long-lived allocation.

882c83f9de Update many_boxes test to scale with heap size (#716)
Instead of using a hardcoded number of boxes, use the HEAP_SIZE constant. This ensures that we get a test failure because of an out-of-memory error when the allocator does not reuse freed memory.
