It looks so ugly for browser does not display all spaces. Let me give more explanation. Display two threads in two collums, every function calling occupy one line. use indent to show calling depth. functions that are called in one function can be folded just as vim fold operation, the thread2 functions should be folded as well according to the folder operation in this thread1.
