Detailed Description

memory object of anonymous type. The object maintains a list of frames.

The object maintains a list of frames and a list of vregions. The lists are backed by slabs. The slabs may have to be grown, in which case the object will use vspace_pinned_alloc.

morecore uses this memory object so it cannot use malloc for its lists. Therefore, this uses slabs and grows them using the pinned memory.
