Here is a summary of ruby-dev.

ruby-dev:22828-22876

[ruby-dev:22841] Process.detach

  Nakada suggested that a thread created by Process.detach should
  returns a value of $?, and Matz agreed with him. So far Thread#value
  always returned nil if it was created by Process.detach.

[ruby-dev:22862] File.fnmatch and Dir.glob

  Yamamoto asked if it was expected that '/' can be included in
  '[]' and '{}' which are described in a pattern passed to something
  like Dir.glob.
  From a section PATHNAMES in a manual page of glob()[1],
    a range cannot contain an explicit `/' character; this would
    lead to a syntax error.
  Matz thought that it makes sence that '[]' doesn't match with a
  pathname containing '/', but it is not useful that '{}' doesn't
  match with that one.
