fault_limits would often hit the 10min timeout and be killed on Fedora 41-42. Investigation showed that the 'fill_fs' portion of the test, which would fill the pool with junk data before vdev replacement, was writing highly compressible data (~126x), which would have taxed the CPUs, potentially causing the timeout. The fix is to write random data and reduce the number of writes. This has an added benefit that more real data being is written to the pool (~1GB) vs the old way (~300-400MB). It also speeds up the test.
