Hi, I am sorry to intrude in this thread. But I think there is a vulnerability in macos caused by ftruncate. For instance running the following code abruptly crashed macos (mojave and catalina).
``` from multiprocessing.shared_memory import SharedMemory shm = SharedMemory(name='test-crash', create=True, size=1000000000000000000) ``` This is being tracked at https://bugs.python.org/issue39584 https://bugs.python.org/issue39584. Could please comment whether this should be fixed by python, or we should wait for a macos fix.
