[sf-perl] threads, threads::shared, and multiple locked variables

I have been experimenting with concurrent programming with Perl, 
threads, and threads::shared.  I have successfully used a shared 
variable, lock(), cond_wait(), and cond_broadcast() to ensure 
thread-safe access to one shared resource.

I would now like to ensure thread-safe access to multiple shared 
resources.  Specifically, if a thread desires access to any one of 
several shared resources, how can it block, wake up when one resource is 
available (and locked), and determine which resource to access?
