Hi, I have just finished integrating MenTaLguY's fastthread mutex implementation into the ruby_1_8 branch. The original, pure ruby version of lib/thread is still available as a configure option `--disable-fastthread' so you can alternate the two. If you find any compatibility problems or unexpected behavior with the new implementation, please let me know. As I tend to be out of sync with ruby-talk, make sure to add ruby-core@ruby-lang to To/Cc on reply.
