libthread-queue-perl 2.11-1 (i386 binary) in ubuntu lucid

 Thread::Queue provides thread-safe FIFO queues that can be accessed
 safely by any number of threads.
 .
 Any data types supported by threads::shared can be passed via queues:
 .
  * Ordinary scalars
  * Array refs
  * Hash refs
  * Scalar refs
  * Objects based on the above
 .
 If not already thread-shared, complex data types will be cloned (recursively,
 if needed, and including any blessings and read-only settings) into
 thread-shared structures before being placed onto a queue.
 .
 This package contains a newer version of the core Perl module Thread::Queue.
 Unless you need a higher version than the one present in perl-modules, there
 is no need to install or depend on this package.
