Yep - the challenge is to:

a) communicate the potential of these tools effectively to new Python users
b) ensure these tools are readily available to them (without turning into a
build nightmare)

A profiling HOWTO (especially one that highlights visual tools like
SnakeViz) may be helpful on the first point, but the second one is a fair
bit harder to address in the general case.
