=head1 NAME

examples/benchmarks/gc_alloc_new.pasm - GC Benchmark

=head1 SYNOPSIS

    % ./parrot examples/benchmarks/gc_alloc_new.pasm

=head1 DESCRIPTION

Makes a big string with C<repeat>, then prints out some statistics
indicating:

=over 4

=item * the time taken

=item * the total number of bytes allocated

=item * the total of GC runs made

=item * the total number of collection runs made

=item * the total number of bytes copied

=item * the number of active C<Buffer> C<struct>s

=item * the total number of C<Buffer> C<struct>s
