Maybe it's better to move the _validate_size to the module level, to avoid coupling between BufferWrapper and a private method?

gh-137928: Refactor to centralize size validation in multiprocessing.heap
Summary
This PR refactors the
multiprocessing.heapmodule by centralizing size validation into a private static method (Heap._validate_size).Previously, the same validation logic was duplicated in both
Heap.malloc()andBufferWrapper.__init__().Changes
Heap._validate_size(size, _maxsize=sys.maxsize).malloc()andBufferWrapper.__init__()to use this method.sys.maxsizeat definition time to avoid repeated global lookups.Impact
