That's exactly why I was proposing a more general solution where you can simply define a function in user-space that will issue a warning or stop on fork, it doesn't have to be part of core R, there are other packages that use fork() as well, so what I proposed is much safer than hacking the parallel package.

Btw. what other packages do fork() without an exec() call()?
