AttendClient of grab-pervious client must queue to saved_ready_clients [v2]

Browse source 
A client which is attended while a grab is blocking execution of its
requests needs to be placed in the saved_ready_clients list so that it
will get scheduled once the grab terminates. Otherwise, if the client
never sends another request, there is no way for it to be placed in
the ready_clients list.

v2: Wrap comment above mark_client_saved_ready.
    Remove test for OS_COMM_IGNORED which will always be true.
