This allows users to invoke xm against a remote server. This is much more
useful though for exercising XML-RPC transports with xm-test though since
xm-test will continue to (mostly) function if the URI is localhost.

This command proxies the Xend XML-RPC over stdio. This is similiar to
mercurial's hg serve --stdio command.
The most obvious use of this command is remote XML-RPC invocation over SSH.

This patch fixes a few bugs in the Python SimpleXMLRPC server and enables
HTTP/1.1 by default. This allows a client to use Keep-Alive. Keep-Alive
improves performance by eliminating the overhead of connection setup and,
more importantly, avoids credential caching when executing multiple
commands over a secure connection.

Lots of xm-test tests are failing with console timeouts on some machines
at the moment. I reproduced the problem and found it was due to some
probing activity in the boot process of the -xen kernel. The behaviour
of the current xm-test code is to assume that the boot process has
finished after performing three one-second waits for input---when the
probing activity introduces more than three one-second delays the test
suite breaks.
This patch changes the test suite to wait for the command prompt
before attempting to submit a command. The timeout is increased from 3
seconds to 3 minutes but the wait exits early when the prompt is found
so the test suite doesn't take any longer to run.

entry conditions to that function. Now that we no longer
check PGERR_page_present (i.e., that fault is a protection
fault), because it's not safe to do so, we can enter
ptwr_do_page_fault() with a not-present L2 page directory.
We then crash on our first access to the linear_l2_table.
This patch fixes all unprotected accesses to the
linear_l2_table to correctly handle faults.
Also move setup of globally-visible ptwr info record to end
of ptwr_do_page_fault(). We don't want the info picked up
by reentrant invocations of the page-fault handler.
