Thanks, but this doesn't really measure memory usage.  It just uses
malloc calls as a poor man's replacement for SIGPROF signal, so the
results show a kind of CPU profile, not memory profile.

More like it's responsible for most of the CPU activity.

And the automatic GCs were much faster?

Thanks.  I hope Carlos will be able to give some hints based on your
data.
