At the kernel level, threads and processes are identical - they each get
a fair share of CPU time. From this we can surmise the cause of any
variation between threads and processes. If the threads are balanced
(each thread completing the same number of requests), but the processes
have unbalanced numbers, we know that X is not as fair.

The kernel checks for past vblanks using an int32_t comparison, so we
can only program up to 31bits into the future (and similarly programing
a timer that large would also overflow).

Given Present bugs, any completion event may be sent too early and
out-of-order. Make sure we drain all outstanding events before
continuing on to the next test.

If the Xserver reports 10 frames passed instantaneously, flag an error
rather than divide by zero.

When we specify a divider we are looking for slightly different races
that are in theory not so timing dependent (since we are using vrefresh
windows). However, since they each take some multiple of vblanks to
complete, they are much slower. We should be able to reduce the number
of iterations without losing detection capability.

Try terminating the client using XKillClient and seeing if we can find
any races with Client shutdown.

A simple demonstration of what may go wrong when a Window is destroyed
by another client such as the window-manager.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
If the window manager closes the Window before the client disconnects,
we can end up with a blocked client as dri2 does not call AttendClient()
in its DRI2DrawableGone.

Originally this was inplace so that we wouldn't simply migrate the
target away from the GPU whenever we inspected results. That is no
longer a problem and so we can speed up the tests by skipping the
temporary.

We shouldn't just discard the mask if the user requests that we render
the glyphs through a low bitdepth mask - and in doing so we should also
be careful not to improve the bitdepth of that mask (since we don't take
into account the extra quantisation desired).
Testcase: render-glyphs

Since the first flip may require a fixup, we will only really know with
the second flip whether we can start a flip chain with different tiling.

As the test presumes we can queue all the modulus queries within the
same vblank, we can improve matters by synchronizing to the next vblank
first.
