Comment 6 for bug 667386

To confirm this scenario, one would need to build HOST_OP=NO and attach to the process with cygwin gdb. One can type "info threads" to see what is running, and "thread nnn" to change the thread context. Once in the right thread one can type "bt" to see the stack.

We are looking to see if a thread "CAS-TCP" (whose task id is seen in casr) is lodged in the function ioctl, and also if the associated "CAS-event" thread (running at almost the same priority) is lodged in the function send.
