If you do something with a debug log (, I’m thinking put a ! at the end of a line). It should put a timeline-marker like the ones when your code times out, except only for debugging your own code.
I thought about putting a “!” in front but that might screw with odd messages like (I would never do) this:
System.err.println("!done: " !done); // Why?!?
So how you would do it is:
java:
System.err.println(“This is an important event!”);
or
python
print(“Important!”, file=sys.stderr)
