Well, it will result in R crashing instead :)

So be careful with this approach - you will get crashes that will seem inexplicable. Also note that calling R from different threads is unsafe unless you also make sure that the error handling doesn't cross stacks or thread boundaries. You should rather enqueue R calls to the main thread, unless you are really a guru and know how to avoid such issues across signals and errors.

Cheers,
