Thanks a lot!!!=20 but i have two more :) 1) in SKAS mode, the tracer (UML kernel) will execute a system call for the tracee (the user process). But what if the system call blocks? then, the tracer, the UML kernel, will be blocked, too, right? it means the whole UML system will be blocked? 2) in TT mode, what if the user process (tracee) installs its own signal handler for SIGUSR2?
