# This module contains entry points to run a single test. runner_init
# determines whether they will run in a separate process or in the process of
# the caller. The relevant interface is asynchronous so it will work in either
# case. Program arguments are marshalled and then written to the end of a pipe
# (in controlleripccall) which is later read from and the arguments
# unmarshalled (in ipcrecv) before the desired function is called normally.
# The function return values are then marshalled and written into another pipe
# (again in ipcrecv) when is later read from and unmarshalled (in runnerar)
# before being returned to the caller.
