This uses the stdlib's method of creating a tempfile in our write file atomimc method, with a few modifications. We use a 64 bit number rather than 32 bit, and therefore a corresponding LCG. This is to reduce collision probability. (Note we currently used 32 bytes previously, so this is likely a concern) We handle reseeding the LCG in such a way that multiple threads are even less likely to reuse the same seed.
