On the [Built-in Exceptions](https://docs.python.org/dev/library/exceptions.html) page, the exception [InterruptedError](https://docs.python.org/dev/library/exceptions.html#InterruptedError) correlates the error with the errno [EINTR](https://docs.python.org/dev/library/errno.html#errno.EINTR), linking the name `EINTR` with the errno page. This is great, since reading "*corresponds to errno EINTR*" is pointless if you don't know what `EINTR` means. The problem is `InterruptedError` is the only exception that put a link on the errno. All others only have the "correspondes to errno `ERRNO`", without any links, which makes it harder to understand.

The same thing happens on the [errno](https://docs.python.org/dev/library/errno.html). On the section about [errno.EINTR](https://docs.python.org/dev/library/errno.html#errno.EINTR) we have a "see also" box saying "This error is mapped to the exception InterruptedError", with a link to the InterruptedError section on the exceptions page. However, for some reason the "see also" box is only on this specific errno section.

The links should be added on both pages so the great pattern defined by `InterruptedError` and `errno.EINTR` is mantained.
