normal 2e87ef8b66 rubyspec/core/io/popen_spec: avoid lingering "ruby -e sleep" process ... The ruby_cmd helper blindly escapes code blocks passed to it, causing "sleep" to be quoted in the command-line. This quoting results in IO.popen using a subshell (/bin/sh) to run the given string command instead of invoking the Ruby executable directly. Thus, IO.popen would only see the PID of the subshell via IO#pid, and merely sending SIGKILL to the subshell would not result in the child ("ruby -e sleep") being killed. This problem with lingering ruby processes was easier to reproduce on slow or heavily-loaded systems using low-scheduling priority (e.g. "chrt -i 0 make test-rubyspec") git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58863 b2dd03c8-39d4-4d8f-98ff-823fe69b080e		2017-05-24 00:34:12 +00:00
