Some example of existing stack-unsafe functions:

• sort - reported in sort and sortBy are not stack safe #192
• nubEq, can be fixed for strict lists by applying same strategy used for struct nub in Match nub* functions with Array #179
• nub for lazy lists. Don't know of a good way to fix this. The strict nub strategy of Match nub* functions with Array #179 cannot be applied here because you can't reverse an infinite lazy list.

We should ideally setup stack-safety tests for every function. To help make those tests run faster, we could shrink the v8 stack size with something like --stack_size=10 (default is 984 kB).
