Another area of overlap is program compilation with programmer
thinking about the problem.  Human instinct can sometimes lead
the programmer to try to "keep up with" the machine and make a
test run as soon as the compilation is done rather than waiting
until the thinking is done.

A faster compiler can result in a considerably larger number of
compilations to reach the same end result, possibly with a much
longer wall clock time.
