Jython logs to stderr, up to a verbosity level of -vvv, a variety of runtime events, most notably in import resolution. The logging code is simple: https://github.com/jythontools/jython/blob/master/src/org/python/core/Py.java#L1992

It would be helpful to get more detailed runtime output by expanding what is logged; choice of output log; and especially with timestamps. Such instrumentation could help diagnose problems in say excessively long import times.

We should look at integrating with some widely used instrumentation package in doing so.
