  in particular it would be useful to document which functions from the mpn layer
  do *not* allocate extra memory (either by alloca or by any other mechanism).
Better mpn docs is on the list.

Why is alloca a problem?  All GMP functions have a stack fram allocated
for them by your compiler.  Isn't that also a problem at the same level
of alloca, which extends the current stack frame?
