=head1 NAME

Cache::SizeAwareSharedMemoryCache -- extends Cache::SizeAwareMemoryCache

=head1 DESCRIPTION

The SizeAwareSharedMemoryCache class adds the ability to dynamically
limit the size (in bytes) of a shared memory based cache.  This class
also implements the SizeAwareCache interface, providing the 'max_size'
option and the 'limit_size( $size )' method.

=head1 SYNOPSIS

use Cache::SizeAwareSharedMemoryCache;

my $cache = 
    new Cache::SizeAwareSharedMemoryCache( { 'namespace' => 'MyNamespace',
                                             'default_expires_in' => 600,
                                             'max_size' => 10000 } );

=head1 METHODS
