How? For what I learned each process executing on a OS with an mmu sees 
its virtual address space, and normally only its code is loaded there 
(well I am learning that the dynamic linker also inject into that space 
shared library code used by the process code, but of course a good 
dynamic linker would prevent clashes!) so how can it happen that it can 
clash with anything??
If I remember fine, at the time of DOS there were some addresses 
reserved for the OS, and then only one executable could run at time, but 
in modern time with virtual addressing I don't think it is possible 
other than in scenarios alike ours..
