        Yeah, but when each such common block is allocated a full page (or 
whatever size the linker/OS swapper uses) it gets a bit wasteful of 
memory (the physical memory of my college Sigma-6 was only around 
1MByte, and had to support ~50 active user terminals... 50 "global" 
integers would have taken 25KBytes of memory on page alignments).
