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.	6 years ago

libs/cmn/writefileatomic: Handle file already exists gracefully (#2113 )

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.
