Since I started this, I might as well finish it. I do have some Python developer experience (hey, I even voted for comp.lang.python back when...) but not in the core interpreter itself.

What would be really spiffy is to provide a way for externally-triggered thread dumps. This is one of my top two Java features [1]. The way this works in Java is a bit awkward -- "kill -QUIT" the Java process and it writes a traceback for every running thread to stdout -- but it works. Something similar ought to be possible for Python, although optional (because Python apps can handle signals themselves, unlike Java apps).

It could be as simple as this: calling

sys.enablethreaddump(signal=signal.SIGQUIT)

from the program enables externally-triggered thread dumps via the specified signal.
