Hello,

while playing with rt_pipe, I realized that a select()/poll() function
does not unblock when the rt_pipe is deleted (via rt_pipe_delete) on the
other end. I think this is because the poll callback does not support
POLLHUP:

Is this by purpose? At least a blocking read() works as expected. It
does unblock and return 0 in that case.

Wolfgang.
