One example that I came accross recently is operating system code. If
you're writing scheduler code, memory manager code, I/O driver code,
you frequently have to deal with the segment architecture on the x86
processors. The only workaround is to put lots more assembler than I
am really comfortable with as a potential inspector of other people's
code:-)
