This decreases the quality of the seeds during the test, it does not affect
the seeds outside the test.
There is a small chance that this causes test failures, if that happens
the threshold needs adjusting
Testing on an idle x86_64 system shows that this passes even with the test
strength
increased to 32768 from 256 with 0 retries
So test failures are not anticipated
Lowering the threshold from 3 to 2 causes failure at test strength of 32768
