$NetBSD: patch-lib_rdoc_ri_driver.rb,v 1.1 2020/03/15 15:26:22 taca Exp $
* Defer loading readline, when it is really needed.
Some unknown reason:
1. build devel/ruby-readline with editline(3).
2. Execute a ruby script loading readline in background from shell.
3. When the script output something to stdout, it got SIGTSTP and suspends.
There is no such problem when build devel/ruby-readline with GNU's readline.
