Bug description:
  == SRU Justification ==
  [Impact]
  When the system is under memory pressure, the entire desktop session may crash.

  [Fix]
  Commit f9d8d9acbb6a620684fb4dac4affe25816587d92 ("iris: Avoid abort() if kernel can't allocate memory")

  [Test]
  Run memory stress and the session crashed in less than 5 minutes.
  With the fix applied, run memory stress for 24 hours and the desktop session is still alive.

  [Where problems could occur]
  Doing a reset might make the system even more sluggish when under memory pressure.

  
  == Original bug report ==
  I run checkbox job com.canonical.certification::memory/memory_stress_ng on focal, and the xserver stops unexpectedly with the following stacktrace:
