[erlang-questions] Crash on alloc

[Francesco Cesarini (Erlang Training and Consulting)]

What it fails to allocate does not include the memory which has already 
been allocated. Memory is allocated when needed... And as Erlang lacks 
Lazy evaluation*, this is the result when dealing with large data 
structures.

* You can simulate lazy evaluations using Funs.
