debug issues.

went to enable this and it is really odd to have to edit a config file to
enable debugging. How about hooking it into verbose option? Maybe like
multiple levels of -v or -v <val> or -v queue.

seems like verbose option factoring.. in future ;-) I can live
without this patch though.. it was mainly for testing my changes

It was quite useful to see how various data sets were stressing the ordered samples queue. For example 'perf record -g' and a kernel build stressed it more than the record on the 'perf bench'.
