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. */
