Just a small note, the global 'numa' variable was NOT used to track whether libnuma had been intialized or not. The user used to specify smp or numa, then we decided that we would remove the numa option. What happened was that if numa was available and smp was not specified the program would automatically use numa else it would use smp. If smp was specified then smp was used. The numa variable would track that. the smp option used to just collect a common set of options -a -t and priorities all the same.
