merge revision(s) 42439,42453: [Backport #8752]

	* test/coverage/test_coverage.rb (TestCoverage#test_big_code): use `1'
	  instead of `p' to get rid of a side effect.
	  Kernel#p without any argument seems to do nothing, but flushes stdout.
	  and, if stdout is redirected to file, fsync() will be called on
	  Windows.  so, when running test-all on Windows with redirection, such
	  as CI environment, this test took a lot of time.
