There are options to increase space allocated to the stack.
However, it is a bit tricky to pass them to sbcl. Probaly
better alternative is to find out what causes large stack
usage and change code to use heap. In particular in many
cases library code uses recursion to process lists. If
lists are short this is OK, but otherwise leads to stack
overflow. So we need to find places which use recursion
on long lists and change them to iteration.
