When we test


sage-doctest writes


runs the new file through python, and deletes it. This can cause collisions when we test in parallel multiple files with the same basename, e.g., __init__, all, misc, conf, constructor, morphism, index, tests, homset, element, twist, tutorial, sagetex, crystals, cartesian_product, template, ring, etc.

There's a similar problem with testing non-library files, which sage-doctest first effectively copies to SAGE_TESTDIR.

See sage-devel for background.
