Comment (by meejah):

 I tried the new py.test based tests on a windows VM, and they don't
 "quite" run. The problem is the "restart Alice and Bob" piece. This is
 required by magic-folders (after the invite/join), but it's also somewhat
 "weird" that "tahoe start" on Windows does a very different thing than
 "tahoe start" on other platforms.

 Although it would break the CLI "API", I think what would be ideal is to
 introduce a "tahoe run" command that does the same thing on both platforms
 (that is, runs in the foreground) and make "tahoe start" print an error-
 message and exit on windows (i.e. "please use 'tahoe run' instead"). Then,
 the tests can use "tahoe run" and can do their own thing to re-start.
 (Note: "tahoe stop" already fails to work on windows).

 Additionally, perhaps we can remove the need to re-start the client nodes
 when a magic-folder is added?
