Because it only loads and runs a single program.

Imagine the case of an editor which launches the compiler.  v2loadimage 
will load and run gcc.exe, but gcc.exe promptly spawns cpp.exe, cc1.exe 
etc.  The debug support cannot preempt the spawned child (unless you hook 
Int 31h in PM), since you cannot set breakpoints in the child.

But you actually *want* to preempt cpp and cc1, not gcc, since most 
messages are printed by cpp and cc1.
