A multi-threaded user process makes a system call and control comes to kernel extension ( I mean proc_self( ) gives me the pid of the user process). If the kernel extension blocks using msleep( ), does it block the entire process or does it block only a specific thread of that process that is making a call. I am trying to understand the threading model implemented in Tiger.

Each pthread corresponds to a unique kernel (Mach) thread. So msleep () will only block that one thread.
