Ok. But then you still end up with the issue that now the profiles are
different, and you have a 8-byte pointer to dynamically allocated
memory instead of just the simpler comm[TASK_COMM_LEN].

Is that actually a good idea for tracing?

We're trying to fix the core code to be cleaner for places that may
actually *care* (like 'ps').

Would we really want to touch this part of tracing?
