- * @brief Allocation/deallocation function for use with Variable Length
- * Arrays in spawning functions.
- *
- * These should be the only functions in the Cilk runtime allocating memory
- * from the standard C runtime heap. This memory will be provided to user
- * code for use in VLAs, when the memory cannot be allocated from the stack.
- *
- * While these functions are simply passthroughs to malloc and free at the
- * moment, once we've got the basics of VLA allocations working we'll make
- * them do fancier tricks.
