Here is a summary of articles posted to ruby-dev ML last week.

[ruby-dev:25713] pthread trouble on sighandler

  Nagai proposed a solution on signal handlers of ruby that enables
  native thread, and it was tentatively applied to ruby-1.9.
  That solution enables the ruby to ignore signals which are caused
  by other threads.

[ruby-dev:25726] named capture

  Nishiyama proposed that MatchData#[] receives a symbol and a string, and
  returns matched data which is indicated by a label on a regular expression.
  That proposal is for a ruby with Oniguruma as a regular expression engine,
  as Oniguruma has a feature called "named capture" to specify matched strings
  using labels.
