#6 sounds good. But as I'm still experiencing a life in Orlando (with a
couple of teenage girls dragging a couple of grumpy old Dads around
Universal studios), I'll throw something in :-)
Barry's idea sounds reasonable - although a little more elaborate than is
necessary.
Barry calls for all extension authors to modify their extension code. I
can't see a simple solution that avoids this. However, the solution seems a
little over-elaborate.
If we are asking them to change their code, can we investigate whether
asking them to insert a simple:
if (!Py_IsInitialized())
Py_FatalError("Bad Python version"); /* Never returns */
works OK? I believe it will, as long as Python's fatal error handler
doesnt make thread-state assumptions.
Too-much-of-a-life-to-check-ly,
Mark.
