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?
