If I understood this right, then I can use forkIO to run a
"safe" FFI function which blocks, but in the threaded RTS
this will not block all other FFI calls.
Right.
So what happens in the non-threaded RTS? Now the blocking
yet "safe" FFI invocation _would_ block other FFI calls but
not evaluation o

Thanks for the clarification.
