Bug #10202: TestBenchmark#test_realtime_output breaks on ARM
https://bugs.ruby-lang.org/issues/10202#change-48648

* Author: Vit Ondruch
* Status: Open
* Priority: Normal
* Assignee: Akira Tanaka
* Category: 
* Target version: 
* ruby -v: ruby 2.2.0dev (2014-09-03 trunk 47372) [armv7hl-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
I observe following error on ARM:

~~~
  3) Failure:
TestBenchmark#test_realtime_output [/builddir/build/BUILD/ruby-2.2.0-r47372/test/benchmark/test_benchmark.rb:159]:
Expected 1.0 to be < 0.999977873172611.
~~~

It seems to be introduced by r47360. Reverting the commit makes test suite to pass once again.
