Hi Pedro!

I'll take a look at the reviews sometime after I get back tomorrow night.

My general thoughts are: if it's an application of library that needs to be portable, don't use it. If not, use it.

I think it's kind of the same class of API call as reallocf. reallocf is a good extension, but it's not 100% portable.

Thanks!
