@nagisa: The locals PR is feature complete and is waiting for the final approval at wasmer#128;
@nagisa: I'm currently working on spec and spectests for a green-field instrumentation implementation;
@nagisa: wasmer#125 is something that I think is worthwhile to finish up now that work on function call cost model is nearing completion...
@Ekleog: Collaborate with @Simonas (nagisa) on the instrumentation rewrite
