obreak(2) gets confused over OMAGIC executables. It even unmaps pages
when asked to extend the break under anomalous conditions.

It looks like exec_aout.c should be more careful and see to it that the
not unreasonable invariant

	"vm_tsize + vm_dsize == # pages mapped for text/data"

(excluding stack and explicitly mmap()ed pages) is maintained.
