Deprecation warning in Mocha's test

Line 39 in 0a93024

var tmpDir = os.tmpDir().replace(new RegExp(path.sep + '$'), '');

is using os.tmpDir and that's printing a deprecation warning.

Depending on supported versions of Node and how far back the replacement os.tmpdir goes, we may have to dynamically detect the availability of os.tmpdir.

Otherwise, we should just change that one letter and be done with it.
