Hash :fec696e8 Message :Grab the kernel lock in pgsigio() as it's strictly needed while
operating on the process structure and issuing signals. This is similar
to what sigio_setown() already does.
With this in place, the pipe subsystem is no longer required to grab the
kernel lock before calling pgsigio().
