Backport #3639
Updated by jeremyevans0 (Jeremy Evans) almost 5 years ago
=begin Not sure if there's going to be another 1.9.1 release, but when using IO#read_nonblock, I've seen rb_bug() from rb_sys_fail() because errno == 0 under 1.9.1. So r27401 from 1.9.2/trunk should fix the issue, but I'll probably abandon 1.9.1 for 1.9.2 soon anyways. =end
