In detail:
- Performance is much improved: programs typically run 1.20--1.40 times
- faster under Memcheck, with an average of about 1.30 for the programs we
- tested it on. The improvements for Nulgrind are similar. We haven't
- measured Cachegrind and Massif, they should be also be faster, but with a
- smaller improvement. We are interested to hear what speed-ups users get.

- Memcheck uses much less memory. The amount of shadow memory used -- which
accounts for a large percentage of all of Memcheck's memory overhead --
