Syntax: !mmrecycle [y|n]There is a memory manager mode, where for certain frequently used list elements, the elements are never freed but are instead ``recycled'' when needed. This should improve performance for certain operations such as geometry computation, at the cost of keeping memory in use that can potentially be freed (but can be truly freed later with the !mmclear command).
Without an argument, the recycling mode is toggled, otherwise the mode is set according to the ``y'' or ``n'' argument. Switching recycling off does not free the free lists, use !mmclear to reclaim this memory for other uses.
