=head1 NAME

examples/benchmarks/bench_new.pasm - PMC Creation

=head1 SYNOPSIS

    % time ./parrot examples/benchmarks/bench_newp.pasm

    % ltrace -crT ./parrot examples/benchmarks/bench_newp.pasm

    % valgrind --tool=callgrind ./parrot examples/benchmarks/bench_newp.pasm
    % callgrind_annotate `ls -rt callgrind.out.*|tail -n1`

=head1 DESCRIPTION

Creates a C<ResizablePMCArray> PMC and fills it with C<Integer> PMCs. 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
