Feature #11081: [PATCH] stdlib: use IO#wait_*able instead of IO.select when possible

• Status: Closed
• Assignee: akr (Akira Tanaka)
• Target version: -

[normalperson (Eric Wong)]

In case a process encounters high-numbered FDs, this allows
consistent performance on systems with ppoll support.
[ruby-core:35572]

• ext/socket/lib/socket.rb (connect_nonblock): use IO#wait_writable
• lib/drb/drb.rb (DRB::DRbTCPSocket#alive?): use IO#wait_readable
• lib/webrick/httpserver.rb (run): ditto
• lib/resolv.rb (request): ditto for single socket case

Pretty trivial since io/wait seems supported everywhere nowadays.
Any objections?

• Status changed from Open to Closed

Applied in changeset r50432.
