#454 Create file in pytest's tmpdir, not in /tmp.

[hiker]

Use pytest tmpdir (which is cleaned up automatically), instead of /tmp for temporary files (over 220 files per test run). Fixes #454.

Thanks for fixing this Joerg. I confirm that running the test suite no longer puts files straight into /tmp.
No other updates required.
Will proceed to merge.
