Get the approximate peak memory usage since the last call to memory_usage_peak_reset. This is approximate, because the peak usage is not updated after every allocation (see peak_update_threshold).

In the worst case, the peak memory usage is underestimated by peak_update_threshold * #threads. After large allocations (larger than the threshold), the peak usage is always updated so those allocations will always be taken into account.

Clear the listbase of allocated memory blocks.

WARNING: This will make the whole guardedalloc system fully inconsistent. It is only indented to be called in one place: the destructor of the #MemLeakPrinter class, which is only instantiated once as a static variable by MEM_init_memleak_detection, and therefore destructed once at program exit.
