Hello Bart,


I dont know systemtap all that well, other than what i have
read on the net and browsed in the source. systemtap is similar,
but dtrace provides a high level functional language (D) and
a set of methodologies and scripts which mean learning/training
will make it easier to use.

In addition, dtrace promises to be kernel safe (whether or not it
is will be down to how good a job I do I guess!)
