>Description:

We have functions to set and get a thread name (pthread_setname_np
and pthread_getname_np), but I couldn't find a userland utility to display
them. These is very usefull in heavily threaded apps like Firefox (which
can be taught to properly set thread names).

FreeBSD seems to have a procstat utility for this.
If we find spare option letters, we could also add it to ps(1), and a
top display including it would also be nice.
