Hi Niall,

I don't use embedding, so I am not sure this is relevant, but ever since I
started importing all extension modules with RTLD_GLOBAL under Linux I've not
observed exception handling problems anymore. I.e. I am doing the exact
opposite of what I understand you are suggesting above. Here is my trick,
the "import_ext" function:

Does it make sense to you that this approach seems to fix the EH problems? (Or
am I just lucky? Hope not.)

Ralf
