If memory serves me correctly, some programs such as Optimem don't actually
compress RAM, but are more efficient in managing the memory that is being
used, avoiding the frequent and tedious writes to swap that Macintosh
virtual memory is infamous for (ever used VM with photoshop?). About being
coded out, you are correct - a disassembler can only rebuild code that was
directly put in the executable, although I suppose an unused subroutine
could be compiled into an executable, but never called. In summary, Optimem
doesn't use the Mac's PMMU, doesn't compress memory, but does use dynamical
memory allocation. So, compression isn't a must...
