DTrace for Linux

[Stone, Joshua I]

This is getting a lot of buzz on the blogosphere:
http://blogs.sun.com/roller/page/ahl?entry=dtrace_for_linux

Using BrandZ and Dtrace, he was able to root-cause some problem with the
Linux "top".

Looking through his scripts, I think that a lot of his analysis could be
done *today* with SystemTap.  There's some user-mode stuff that we can't
do, but most of it seems ok.

It would be nice if we could duplicate his results using SystemTap, to
show our current maturity...
