This is what causes CRIU dump to fail. Thunderbird uses SysVIPC shared
memory mapping, but we can't dump only _it_ as there's no way to find out
what other process might be using the same shared memory segment.

Actually, dumping X-application is quite a challenge as part of the app's
state is in the X-server and we have some way to dump it as well. We haven't
yet looked into this.

If you want to play with X-applications you may consider playing with VNC:

Thanks,
