This change is incorrect - "unacceptable" is exactly what the writer
wanted to say here.

of the timers.c code in an unacceptable way*

equals

*it can be 'designed out' ... in an acceptable way*, I think.

So, just from semantics, my feeling is, *it cannot be 'designed out' in 
an acceptable way* is the reason why integration is hard. Am I still wrong?

The original author, clearly, was talking about the degradation being
unacceptable.  It seems clear enough, I don't think that change should be
made.

Thanks,
