Due a bug - we never checked the time_travel_ext_free_until value - we were always requesting time for every single scheduling. This adds up since we make reading time cost 256ns, and it's a fairly common call. Fix this. While at it, also make reading time only cost something when we're not currently waiting for our scheduling turn - otherwise things get mixed up in a very confusing way. We should never get here, since we're not actually running, but it's possible if you stick printk() or such into the virtio code that must handle the external interrupts.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
