=head1 NAME
examples/benchmarks/gc_generations.pasm - GC Benchmark
=head1 SYNOPSIS
% ./parrot examples/benchmarks/gc_generations.pasm
=head1 DESCRIPTION
Runs a loop several loops, each making big strings 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
