I actually did something like this for top. In top I had > all mutex names start with a * to differentiate them from wait channel names, can you do a similar thing for mwchan? Actually, I dont mind either way, but I do very much like the '*' in top, so if anybody puts chans and mutexes in ps output in a single merged field, then please do the same. It's easy to tell that "Giant" is a mutex since it is so recognizable, but what about "tlb"? is that a wchan or a mutex name?
