Comment (by daira):

 twistd sets umask to 0077 by default, unless overridden by
 [https://twistedmatrix.com/trac/ticket/966 --umask].

 The correct approach here seems to be to save the original umask for later
 use by `_write_downloaded_file`, before passing control to twistd in
 `tahoe start/run`. (We don't want to change the umask of the node from
 0077 using `--umask` because that would have difficult-to-review security
 consequences.)
