I was going to ask how this compares to dtrace. With proper userspace support, with this eventually allow similar tracing?

There is already an open source tool providing many of the DTrace capabilities called SystemTap which was started a couple of years ago by a group of developers from Red Hat, IBM, Intel & Hitachi:

http://sourceware.org/systemtap/

Currently SystemTap is focused on kernelspace probing, via the kprobes capability. This new UTrace infrastructure has potential as a way to let SystemTap probe userspace too. Another project which may be able to make use of UTrace is Frysk, which is a broader userspace debugger / execution analysis tool:

DTrace is open source since the beginning.

Yea. And 'FREE software' also, buy the RMS/FSF definition.

Just not GPL-compatable.
