It's not that simple.  Two different shared memory regions would mean
different mount tables, tty tables, pid tables, etc.  because you had
two different versions of cygwin on your system.  One program would not
be able to correctly use a tty allocated by another.  That would end up
causing at least user confusion, if not program confusion.

There is no reason to have two versions of cygwin1.dll on your system.
In 1.1.4 I've made the error message for this scenario a little clearer
so hopefully people will figure this out.
