Node.init_tempdir sets tempfile.tempdir so that Twisted Web will write uploaded files to a node-specific directory.

tempfile.tempdir is global state and mutating it for a particular Node instance causes all kinds of problems (for example, it means you can't really have two Node instances in one process; it also wreaks havoc on the test suite).

Get a feature into Twisted so that Twisted Web doesn't rely on this global state for upload file location and then use that feature instead of mutating tempfile.tempdir.
