Hi again, The unz connection is non-blocking by default. I checked do_unz which calls R_newunz which calls init_con and the only place in any of those functions that sets 'blocking' is init_con which sets it to FALSE: https://github.com/wch/r-source/blob/0c26529e807a9b1dd65f7324958c17bf72e1de1a/src/main/connections.c#L713 I'll open an issue on R-bugzilla and see if they're willing to do somethi...

Thought I'd try and start a discussion. Feel free to jump in. I guess R needs to strike the right balance between opening up the internals to package writers and not allowing them to do bad things. My first attempt at cracking this nut is to just memcpy() the Rconnection and not allow access to the private stuff: /* Alternative to allowing C code access to connection API. */ Rconnection
