I like this proposal.
It looks very similar to one I made five years ago on this thread:

www.ruby-forum.com/topic/135822

The key, of course, is to associate a (hidden) queue with each thread
for incoming exceptions from other threads.
This essentially makes Thread#raise analogous to Queue#push

Kosaki,
  Was my old post any sort of inspiration for this, or did you
arrive at the same solution independently?  You add the ability to
assign different exception delivery policies to each subclass of
Exception.
This seems good on the surface, but won't it complicate the queue
management and make it possible for exceptions to be delivered out of
order?  Have you thought about this?

Charlie,
   Five years ago, after a bit of arm twisting, you admitted that this
technique could allow thread.raise to be used safely. Why the change of
heart now?
