Details:

When I create a sample program that uses the default_pager_object interface
to create a new memory object it fails.  I'm running the program as root.

1. open the /servers/default-pager file
(this is running /hurd/proxy-defpager)

2. call default_pager_object_create, and try to make an object of 4k.

The call fails with a server died message.

This mail message shows a similar error:

Fixing this bug would help tmpfs run correctly.
