The above link has some related discussion, but there is no conclusion at the time, now I don't know how the results, I have said that there is no real thread under Linux, which is implemented using the process simulation, and has an auxiliary thread. Get taken into account when calculating the number of threads.
Use ps -ef f to display the process tree of the ASCII ART mode
PStree -C has the same effect
