Alloca allocates memory using stack pointer increment. This memory is 
reclaimed when you return from a function and the stack pointer is set 
back to what it was. Alloca is the fastest way to allocate memory. 
Another funny thing is, since stack is a GC root, the memory you get 
using alloca also is - so it is safe to store pointers to GCed memory 
there as well.

Most of the time :D. It is _possible_ to get it to grow up, I believe,
and don't quote me on it, but I suspect other architectures have their
own conventions.
