+.. function:: getallocatedblocks()
+
+ Return the number of memory blocks currently allocated by the interpreter,
+ regardless of their size. This function is mainly useful for debugging
+ small memory leaks. Because of the interpreter's internal caches, the
+ result can vary from call to call; you may have to call
+ :func:`_clear_type_cache()` to get more predictable results.
