In this "SASOS" project we explored the potential for "single address-space operating systems". In the mid 1990s there was a lot of interest in operating systems that used a single, large address space, made possible by the new 64-bit microprocessors, to hold all processes and persistent data. Although the concept was interesting, it required an address to be used once and then never reused. We actually measured the usage of live computer systems to get a good estimate on how quickly such an address space would be consumed [kotz:jaddrtrace].
