I'm not familiar with the meaning of transactions in this context, but I agree giving visibility of these remaining events is a good idea. I'm just unsure where to place them from the available --itrace options.
Regarding the "all" events, we thought having quick access to a global histogram of all the spe events is useful, and from all the --itrace options it seemed to fit best under --itrace=o.
Thanks, German
