Comment (by zooko):

 Replying to [comment:3 warner]:

 > In particular, I think that {{{twistd}}} has been loadable as a library
 for several years now, so I think that the subprocess-spawning done by
 {{{tahoe start}}}/{{{tahoe run}}} can go away, which might remove one of
 the needs to change PYTHONPATH. (the test_runner code that really does
 want to spawn a subprocess, because it wants to kill the subprocess, may
 be replaceable with an {{{os.fork}}} or something, so the child can simply
 inherit the environment of the parent).

 Brian made this change in [20101027061342-1477d-
