probes.h is auto generated and it can certainly be massaged to include
the above logic, but I'd like to avoid doing that if possible.
The thinking initially was to make this tracing feature more like a
"framework" and make it as simple as possible to add new probes and as
un-intrusive as possible, that's why I thought and still think that
putting the includes in c.h makes sense, unless there are obvious
disadvantages I'm not aware of.
