I vaguely remember having read here about 'clever code' which took into
account the time a magnetic drum needed to rotate in order to optimise
access.
Similarly I can imagine that with resource restraints you sometimes need to
be clever in order to get your program to fit. Of course, any such
cleverness needs extra documentation.
I only ever programmed in user space but even then without lots of comment
in my code I may already start wondering what I did after only a few months
past.
