It has to free all the memory, if the kernel is worth anything. If it
didn't free all the memory then you would run out after netscape
crashed a few times. Just imagine what your uptime would be like
then!
Any decent kernel/system will take care to release all resources a
process was using after it is no longer running. This includes
memory, files, etc. (This isn't to say that the files, etc, will
necessarily have the values you expect them to have; just that they
will be released (closed for files) and other processes will be able
to gain access)
