`tid`s for `quippy` interface appear to not be always unique #5

Closed sirmarcel closed 5 years ago

Occasionally execution halts with file ready exists due to the quippy scratch folder tid not being unique. This should not happen. It Should Be Tested whether this is actually due to not enough entropy in generating these + the timing being exactly the same, or whether there is a more fundamental problem (which seems a lot more likely.)

If it's actually a randomness problem, fixes could be:

Switching to time_ns
Adding geom_hash
Adding a context-supplied random seed

Seems to be fixed, has not occurred with new cmlkit version.
