Well, the successful five Mega-SLOC project never traced a problem to the use of malloc and free. And it had LOTS of tasking--in fact, being an early Ada project, there was a heck of a lot of over-use of Ada features. Nested generics, multi-discriminant variant records, tasks everywhere, etc. Any feature unique to Ada just HAD to be used if possible.
