Is there any benefit to use multiple heaps for memory management purposes?

Question

I am a student of a system software faculty. Now I\'m developing a memory manager for Windows. Here\'s my simple implementation of malloc() and free():

Answer 1

The only time I ever used more than one heap was when I wrote a program that would build a complicated data structure. It would have been non-trivial to free the data structure by walking through it and freeing the individual nodes, but luckily for me the program only needed the data structure temporarily (while it performed a particular operation), so I used a separate heap for the data structure so that when I no longer needed it, I could free it with one call to HeapDestroy.
