We tried that. I don't have the time and I'm sure the perf folks don't
care. I advocate for LTTng because of the support that Mathieu has given
us.

The only other option is to allow LTTng to have access to a couple of
functions that Mathieu helped develop. Otherwise it's forcing me to say
"Thank you Mathieu for all your work, now go F*** off!".

Which appears to be the only option :-(
