[uml-devel] X crash problem

        Hi!

Found it.

Breakpoint 5, update_thread () at sigio_user.c:195
195             block_signals();
(gdb) n
196             n = write(sigio_private[0], &c, sizeof(c));
(gdb) n
197             if(n != sizeof(c)){
(gdb) n
198                     printk("add_sigio_fd : write failed, errno = %d\n", errno);
(gdb) n
199                     goto fail;
(gdb) n
205                     goto fail;
(gdb) n
211             kill(write_sigio_pid, SIGKILL);
(gdb) p write_sigio_pid
$1 = -1

Making this if (write_sigio_pid != -1) kill... makes everything work like a
charm...

(This is UML running on a kernel patched with my tty pollout patche at
www.corewars.org/tty_bugs.diff).
