It's not very common. I can't give any example off the top of my head
where it is used. I'd expect most pointer arrays to be small, and
allocated on the stack.
You may want to have a look at what guile is doing in its interface
between gmp and the garbage collector. I'm sure it has been discussed
before, but I don't remember the conclusions.
