Eric, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

merges r28557 from trunk into ruby_1_9_2. Fixes #4506.

  • io.c (nogvl_copy_stream_sendfile): jump to retry_sendfile directly
    to avoid select() on a socket which TCP state is CLOSED.
