SIGIO and SIGPOLL are the same number.  SIGPOLL and
SIGURG are for ioctl, SIGIO is for fcntl.  SIGPOLL and
SIGURG are SysV-isms, SIGIO is BSD.  It's a mess,
you have to look at all kind of documentation for
the involved ioctls and fcntls to figure it out. I'm not
myself sure that I wrote it correctly without looking
at the source. :-(

There are some cases in which it is not.  If I
remember correctly, one such case is when
you read after writing.

It is, but thanks very much anyway.
