RFR: 8273823: Problemlist gc/stringdedup tests timing out on ZGC

[Thomas Schatzl]

Hi all,

  can I have reviews for problemlist the gc/stringdedup tests for ZGC? They time out a lot in CI currently, and generate a lot of noise.

Testing: CI run with this change does not run the #id4 tests any more

Thanks,
  Thomas
