 Whenever a Python exception is displayed by Julia, `sys.last_traceback` and friends are set. This allows the post-mortem debugger `pdb.pm()` to work. Disable by setting `PythonCall.CONFIG.auto_sys_last_traceback = false`.

+## Asynchronous Julia code (including Makie)
+
+Asynchronous Julia code will not normally run while Python is executing, unless it is in a
+separate thread.
+
+This can be fixed by calling `jl.yield()` periodically from Python code, allowing the
+Julia scheduler to run.
+
+When working at the Python REPL, you may call `juliacall.interactive()` which will allow
+Julia async code to run while the prompt is showing. This will allow interactive plots such
+as Makie to work.
