I am planning to add virtual time line to uml in an effort to simulate a physical machine, and the user specifies the characteristics of physical machine to be simulated.
I understood ptracing in tt mode, but not completely in skas mode. How is ptracing done in skas mode ? why many threads do waitpid on a single userspace thread, whats the logic behind it.
Thanks
