-/* These routines allocate space for an object. The assumption is
- that the object will want to allocate space as it goes along, but
- will never want to free any particular block. There is a function
- to free a block, which also frees all more recently allocated
- blocks. There is also a function to free all the allocated space.
-
- This is essentially a specialization of obstacks. The main
- difference is that a block may not be allocated a bit at a time.
- Another difference is that these routines are always built on top
- of malloc, and always pass an malloc failure back to the caller,
- unlike more recent versions of obstacks. */
