Description
ruby-loco just had a failure on TestIO#test_copy_stream_no_busy_wait
for the first time.
8) Failure:
TestIO#test_copy_stream_no_busy_wait [C:/projects/ruby-loco/src/ruby/test/ruby/test_io.rb:557]:
r58534 [ruby-core:80969] [Backport #13533].
Expected 0.031000000000000028 to be <= 0.016417910447761194.
This was on Appveyor, it passed during parallel, but failed on retry, as TestIO#test_write_no_garbage
failed during parallel, which is common.
I haven't really looked at it, or especially assert_cpu_usage_low
, but a change to loosen the test up would be helpful.
BTW, it was the only failure on r63945. I haven't really analyzed it, but Appveyor does seem slower just in the last day or so...
Thanks, Greg
