The problem here is that unfortunately they *can* occupy the same point 
in space at the same time, with the same bad effects as in science 
fiction movies when one object materializes in the middle of another :-).

The problem is that, for instance, some of your malloc calls will link 
to the cygwin libc, while others (from within the Windows DLLs) will 
link to MSVCRT, and if you free the pointer with the "other" library, 
terrible things will happen.
