Dear hlinnaka,
I once attempted to construct a scenario with multiple backends concurrently
performing the split that leads to gin index corruption. Unfortunately, I did
not succeed. The reason is that ginInsertCleanup requires an Exclusive Lock
on METAPAGE, preventing multiple processes from simultaneously executing the
cleanup.
Maybe I missed something. hlinnaka, do you have any suggestions?
