Comment:

 I think the current code uses the "write-to-temp-file&&close&&rename"
 dance. Zancas was working on a patch to use
 [http://twistedmatrix.com/documents/current/api/twisted.python.filepath.FilePath.html
 FilePath] (#1437) and I saw that his patch simplified the extant "write-
 to-temp-file&&close&&rename" dance by using {{{FilePath.setContents}}}.
 I'll look for the details.
