The order of unit initialization is simply the order in which they are
declared in your program. If you use a unit X within another unit Y, that
that unit X will be initialized before unit Y. All units will be
initialized only once.

This never happens, since the order is simply read from the source. If you
compile your program with -a, you can see the order in which the units are
initialized by looking at the generated .s file for the main program and
by then searching for "INITFINALTABLE".
