Perl extension for sharing data structures between threads
Description
By default, variables are private to each thread, and each newly created thread
gets a private copy of each existing variable. This module allows you to share
variables across different threads (and pseudo-forks on Win32). It is used
together with the threads module. This module supports the sharing of the
following data types only: scalars and scalar refs, arrays and array refs, and
hashes and hash refs.
