So, to sum it up:

- patches #4737 (aka patch-gnumach-user_tss),
  patch-gnumach-3-device_port_fix and patch-gnumach-4-more_ports are
  just bug fixes and can be applied asap.
- patch-gnumach-5-io_per_task turns per-thread i/o permissions to
  per-task i/o permissions, and can be applied if noone objects against
  i/o permissions being per task (this is how it is done in gnumach2
- patch-gnumach-2-default_noio turns i/o permissions _off_ by default.
  This shouldn't be applied until patch-hurd-ioperms is applied and
  xfree86/xorg patched too (something like patch-xorg-hurd-ioperms,
  which will only work for isa boards). People with an
  internet-connected Hurd box will probably want to apply them asap
