So if uw_malloc returns memory blocks which you can reuse in those
handlers than its a bug.
None of the callbacks introduced by the compiler itself will ever touch
memory in the context-local heaps (which is the kind of memory that
uw_malloc() manages). If you follow this same rule in the callbacks you
introduce with your FFI code, everything will be fine.
This sounds like another fact that I should add to the manual. Thanks
for pointing it out. :)
