Hmm! I at least agree I didn't say what I meant <wink>.
I realized PyMalloc plays peacefully with other mallocs as-is. What "breaks
down" is extension to BDW-style GC, where the collector wants to perform
everybody's allocations. IOW, PyMalloc pushes a Python-specific allocation
scheme as far as it's ever likely to go, but that falls short of what BDW
You're not required to solve this. Heck, you're not even encouraged to view
it as "a problem" <wink>.
