Re: [go-nuts] Compiling Go plugins with playground/NACL/GAE-like isolation

For some use cases I am sure this kind of integration would be just fine. But if functions within plugins are called often enough the overhead difference between calling a function in a dynamically linked library (.so) and communicating via a UNIX socket will quickly become non-trivial. Even if

[go-nuts] Golang map is getting corrupted with Memory mapped files

I don't really understand what are you doing. You serialize with gob.Encode, but does NOT deserialize, just use the encoded bytes as the backing memory of an unitialized map. This won't work. Either deserialize with gob.Decode, or use your own custom data structure, which can be backed by memory
