IRB hangs when autocompleting require_relative path at root directory

[tompng]

Description

When you run irb in root directory and tries to autocomplete require_relative path, IRB hangs. IRB tries to search every directory in your system. In my environment, it stops after few seconds with Errno::EPERM. Similar to #606

$ cd /
$ irb
irb(main):001> require_relative 'a

Result of irb_info

irb(main):001> irb_info
