We had a chat about testing these changes, and integrating them into xenopsd.
We agreed that we each had slightly different expectations of what we were 
going to do, and when.   I think we came to the following major conclusions:

  - I will start work on a simple test framework for cancellation,
    hopefully to have first results in a fortnight or so.
  - Once the test framework is available you will fix whatever bugs it
    unearths, then we will rinse and repeat.
  - You will think some more about the possibility of adding cancellation
    to the xl command line tool, but since this is tricky there is no 
    expectation of when it might happen.

In the slightly longer term, we expect:

  - More testing and integration effort from Xapi project members in March
    or April.
  - Investigation of the idea of a xenopsd-based push gate, similar to the 
    current libvirt push gate.

Have I got the main points right, or forgotten anything important?   

Thanks,
Euan
