Not sure what the purpose of your use of such a mutex lock is in your app, but if it's something other than restricting access to some resource amongst some threads handled within a given instance of your rails app running in some process, .... but in terms of rails, I don't think a mutex lock will do what you're thinking it will do if your rails app is running / can run in more than one process (ie via passenger or via a mongrel cluster or ...).
Assuming you aren't talking about dealing with threads within a given process, and you really are trying to restrict access to some resource from potentially multiple process instances of your rails app, then you'll need to use a locking strategy that can be used in a multi process context (ie like via your app's db, or potentially via files, or ...). Note however that if you are only running one instance or rails, ie a single instance of webrick or mongrel, then your rails app is essentially single-threaded (running in a single process) in terms of requests handling. In such a single-instance setup, you likely wouldn't need the use of mutex (unless your dealing with threads in that single process) since your app would only be able to handle one request at a time anyway.
