// A `GTrashStack` is an efficient way to keep a stack of unused allocated
// memory chunks. Each memory chunk is required to be large enough to hold
// a `gpointer`. This allows the stack to be maintained without any space
// overhead, since the stack pointers can be stored inside the memory chunks.
//
// There is no function to create a `GTrashStack`. A `NULL` `GTrashStack*`
// is a perfectly valid empty stack.
//
// Each piece of memory that is pushed onto the stack is cast to a
// `GTrashStack*`.
//
// There is no longer any good reason to use `GTrashStack`.  If you have
// extra pieces of memory, `free()` them and allocate them again later.
