Procman, which is hoped to be a replacement to gtop, does this. I used
pretty much the same method of determining whether the process is a
thread as you did by seeing if the process has the same name and same
memory usage. Procman defaults to not showing the threads at all in
hopes that these kinds of questions won't be asked again. Otherwise the
string "thread" is appended to the process name. You can see it in
action here:
