Feature #4528: [PATCH] ext/io/nonblock: avoid unnecessary fcntl F_SETFL calls

• Status: Closed
• Assignee: kosaki (Motohiro KOSAKI)
• Target version: 1.9.3

=begin
Avoid F_SETFL if we're not changing the O_NONBLOCK bit. F_SETFL
is an expensive operation since it needs to affect all processes
with the same file object.

rb_io_set_nonblock() implements similar logic to avoid F_SETFL
in io.c
