* 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.
