- vetinari 14y agoYes, they do, but it is shared, copy-on-write (read-only for .text), meaning that although each running process has it mapped into its memory space, there is only one copy in physical RAM.
- sambeau 14y agoFor some reason I thought that was a fallacy. I must now go and re-read Tanenbaum.
