As an example, Javascript (Spider Monkey) has been annotated with
DTrace USDT (User-Level Statically Defined Tracking)

The write up at
    http://blogs.sun.com/brendan/entry/dtrace_meets_javascript
with an expanded write up at
    http://www.solarisinternals.com/wiki/index.php/DTrace_Topics_JavaScript
shows the sorts of counts and times and execution flow
of the *Javascript* subroutines that can be obtained.

QUESTION: Is this the sort of thing that is being asked for for PIR-level
profiling?
