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.

Regards,

The version of fastthread which was merged doesn’t handle interrupted  
waits correctly, which can result in an rb\_bug().

Please see Ruby bug #8663:

[http://rubyforge.org/tracker/index.php?func=detail&aid=8663&group\_id=426&atid=1698](http://rubyforge.org/tracker/index.php?func=detail&aid=8663&group_id=426&atid=1698)

A patch to fix the issue is attached (also posted to the bug tracker).
