[Windows] Multiple Calls to psutil.users() Deallocates None

[blackadar]

Summary

• OS: Windows 10
• Architecture: 64-bit
• Psutil version: 5.8.0
• Python version: 3.8.5
• Type: core

Description

Calling psutil.users() approximately 4,850 times will end in:

Fatal Python error: deallocating None
Python runtime state: initialized

This can be shown by aggressively calling the function, for example:

import psutil

def main():
    i = 0

    while True:
        print(i)
        psutil.users()
        i += 1


if __name__ == '__main__':
    main()

I'm assuming this could be similar to this issue using Py_DECREF(Py_None).
