Motivation:
NIO has allocation counter tests, NIO also has dev/malloc-aggregation.d
which can give you aggregated stacks that allocated alongside how many
times they allocated. What's missing is a script that can diff two
aggregated stack traces.
Modifications:
Add dev/stacktrace-dtrace which allows aggregated stack trace diffing.
Result:
Easier to track performance regressions.
