You might try something like this:
fd <- openFd ...
I'm not in a position to try it in exactly the same situation, but
I see that when I run with all signals blocked as above, after a while
I have a SIGALRM pending (with -threaded or not), so I reckon that might
be the signal used by the runtime thread manager. If it works, I would
recommend blocking only that signal during the openFd, so for example
you'll be able to abort normally with SIGINT if the device is stuck.
