Andrew: Thanks for answering my questions. Just trying to get a handle on the situation.
The mmap readahead cache is noted as experimental. Since you were getting error messages from it, I assume that there is a bug in it somewhere, so you probably shouldn't use it. I'll continue looking at your issues today. The first thing that I am going to do is download the tar ball and run parallel make in my environment and see what happens.
