test: attempt to reduce failures in assert_cpu_usage_low
Try to make this test less fragile by taking into account
the worst case kernel timing resolution.
[ruby-core:81540]
* test/lib/test/unit/assertions.rb (assert_cpu_usage_low):
clamp measurement to minimum measurable time and warn
about tests being too short to measure
* test/ruby/test_io.rb (test_copy_stream_no_busy_wait):
remove pct kwarg and rely on assert_cpu_usage_low defaults
