While that's true, there is a problem with the patch I posted:
"ReserveAlloc" is not enabled when called from C. I can't actually
reproduce the issue locally due to lack of RAM connected to an ARM
CPU, or I'd have noticed that... I'll attempt to do something about
that upstream[1], let's see... if not, we can still use the new
in-tree SectionMemoryManager, but we'll still need some C++ glue code.
