Hello Minchan and others, I just noticed that the data structures used by zsmalloc have the potential to tie up memory unnecessarily. I don't call it "leaking" because that memory can be reused, but it's not necessarily returned to the system upon freeing. I have no idea if this has any impact in practice, but I plan to run a test in the near future. Also, I am not sure that doing compaction in the shrinkers (as planned according to a comment) is the best approach, because the shrinkers won't be called unless there is considerable pressure, but the compaction would be more effective when there is less pressure. Some more detail here: https://code.google.com/p/chromium/issues/detail?id=408221 Should I open a bug on some other tracker? Thank you very much!
