it might make sense to provide a bit more consistent environment for tests.
eg. create a tty for fd 0-2

a few possible places where it can be done:

  • someone who invokes our test runner (as of today)
  • our test runner
  • runtime adapter
  • runtime itself

open questions:

  • how much flexibility do we want? is it good enough to always assign fd 0-2 to a tty?
  • do we want to support runtimes which don't "share" fd 0-2 with host fds?
  • what to do for non-posix host?
