[issue39164] PyErr_GetExcInfo does not allow to retrieve for an arbitrary thread

[Julien Danjou]

New submission from Julien Danjou :

PyErr_GetExcInfo does not allow to retrieve exception information for an 
arbitrary thread. As it calls `_PyThreadState_GET` itself, it's impossible to 
get exception information for a different thread.
