Awesome, thanks. > I still struggle to understand why stateless lib hierarchy can be problematic. As I said already, I wrote my remark as a general comment. It is just a matter of time when perfectly working system will be changed to less working one. So when you and Alexander are focused to see what is wrong now, I see what can be in the future. To make it clear, even for people who sentimentally attached to libeth code: I didn't ask to change anything, just tried to understand why you did it like you did it. > The fixes that you linked relate more to problematic resource sharing, of > which > libeth has none, it does not have its own memory or its own threads, this is > just collection of data structures and functions.
