    - #### umask

          public static int umask​(int mask)

    - #### uname

          public static PyTuple uname()

      Resembles CPython's uname with the addition that we also attempt a Windows-equivalent variant on win-systems. Implementation overview:
      Original/CPython (POSIX only):
      (uname -s, uname -n, uname -r, uname -v, uname -m)
      This version (non-Windows):
      (property os.name, InetAddress.getLocalHost().getHostName(), property os.version, uname -v, uname -m)
      Adjustments on OSX:
      Normalize "Mac OS X" to "Darwin",
      uname -r instead of property os.version
      Fallbacks:
      nodename/uname -n: exec uname -n
      version/uname -v: ""
      machine/uname -m: property os.arch
      This version (Windows):
      (reproduces platform.uname behavior on Windows)
      ("Windows", InetAddress.getLocalHost().getHostName(), property os.name: part after "Windows", cmd.exe /C ver: part after "Version", env PROCESSOR_ARCHITECTURE)
      Fallback for nodename/uname -n on Windows:
      - env USERDOMAIN
      - exec hostname
      For machine-entry on Windows this is a simplified description. It is actually mapped to typical uname -m values as follows (pseudo-code):
      PROCESSOR_ARCHITECTURE = x86 and PROCESSOR_ARCHITEW6432 undefined: "x86"
      else if PROCESSOR_ARCHITECTURE = x86: PROCESSOR_ARCHITEW6432 else: PROCESSOR_ARCHITECTURE
      Potential flaws:
      - could be a 32-bit machine, but actually not i686
      - user might need to discriminate AMD64 from EM64T
      In the rare case that your application is sensitive to one of these flaws you shouldn't be using our uname-hack for Windows, but directly look at PROCESSOR_ARCHITECTURE and friends.
      Returns:
        PyTuple containing sysname, nodename, release, version, machine
