christos cbb9bcafa0 PR/8247: Simon Burge: monop(6) save/restore doesn't work.
With the advent of elf and mmaping malloc, assumptions that the code made
before about location and contents of the data segment broke. We supplied
an sbrk() only malloc, and recorded the break point at the beginning of
the program, so now save and restore works, in the traditional monop style.
