Bug #12505: Increase memory usage on test-all from r55297
https://bugs.ruby-lang.org/issues/12505#change-59298

* Author: Hiroshi SHIBATA
* Status: Closed
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.4.0dev (2016-06-18 trunk 55443) [x86_64-darwin15]
* Backport: 2.1: DONTNEED, 2.2: DONTNEED, 2.3: DONTNEED
----------------------------------------
Some CI instances have `Cannot allocate memory - fork(2)` issue.

ex.
http://rubyci.s3.amazonaws.com/debian8/ruby-trunk/log/20160618T093002Z.fail.html.gz
http://rubyci.s3.amazonaws.com/centos7/ruby-trunk/log/20160618T100002Z.fail.html.gz

These instances have 1GB RAM. But this issue does not happen before r55297 or r55298.

Doese anyone know cause of this issue?
