On the other hand, recent improvements in autoconf 2.62 proved that we
were able to speed up testsuite performance by more than 10% by merely
refactoring Autotest output to avoid shell parsing of code that would not
be executed. In other words, the time the shell spends on parsing its
input, whether or not that input is executed, is not trivial.
