One of the scenario I can see an issue happening is when you have a

Hi David,
Thanks a lot for point me to the tests you've added in IGT.
While adding a test with that signals fences imported into a timeline
syncobj out of order, I ran into a deadlock.
Here is the test :
https://github.com/djdeath/intel-gpu-tools/commit/1e46cf7e7bff09b78a24367ddc2314f97eb0a1b9
Much like the sync_timeline_signal(), remove the points from the
timeline so that if the callee is dropping the last reference on the
point's fence we don't end up in a deadlock in
timeline_fence_release().
