Having folks call `gc()` or a `@everywhere gc()` is not a good option.\r\n\r\nExplicitly calling finalizers help a lot (not fully as effective as a `@everywhere gc()` which releases resources even sooner).\r\n\r\nI suspect that both https://github.com/JuliaLang/julia/issues/15155 and https://github.com/JuliaLang/julia/issues/15415 are due to distributed gc not releasing resources quickly
