[issue6284] C/API PyErr_AsUnicode()

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

PyErr_Print seems a too high-level function for this usage:
- it uses sys.excepthook
- it exits the process if the exception is SystemExit (!)

I'd prefer a function similar to PyErr_Display. And sys.stderr should 
not be redirected to a temporary stream: this change is not thread safe.
For example, A new function PyErr_DisplayEx could take an additional 
(PyObject *fp) argument.

As for the Blender use case: isn't it appropriate for Blender to change 
sys.stderr globally, since the console is not used?
