As I already said, there are too many than I want to even spend time
describing any.

Be it just

                 if (ispoll)
                   {
                   case EPIPE:

which is obviously bogus without looking at the context. It's sad that
the C compiler can't tell you it does not make sense (I see what sense
you tried to tell the compiler, but sorry that can't work that way).

               if (d[i].io_port == MACH_PORT_NULL)
                 {
                   _hurd_port_free (&d[i].cell->port,

Doesn't make sense either. You haven't understood what the original code
was doing (cleaning the previously allocated ports, not this newly one).

There are other such kind of issues I don't even want to take time to
look out again.
