Title:
  qemu-alpha linux-user breaks python3.6

Status in QEMU:
  New
Status in Gentoo Linux:
  Fix Released

Bug description:
  Running on Gentoo Linux in a chroot environment:
  # python3 -c 'import selectors; selectors.DefaultSelector()'
  Traceback (most recent call last):
    File "<string>", line 1, in <module>
    File "/usr/lib/python3.7/selectors.py", line 349, in __init__
      self._selector = self._selector_cls()
  OSError: [Errno 22] Invalid argument

  However, on real hardware, with the same binaries there is no
  exception.

  This impacts whole python3 based Gentoo ebuild system (package
  management), and renders linux user mode alpha emulation in chroot
  environment building useless, more or less.

  The used systems:
  # qemu-alpha --version
  qemu-alpha version 4.2.0
