C 3 valloc - aligned memory allocator

 char *valloc(size)  unsigned size; 

Valloc allocates size bytes aligned on a page boundary. It is implemented by calling malloc (3) with a slightly larger request, saving the true beginning of the block allocated, and returning a properly aligned pointer. Valloc returns a null pointer (0) if there is no available memory or if the arena has been detectably corrupted by storing outside the bounds of a block. Vfree isn't implemented.
