Thread interruptable too early?

Hmm. Question.

Imagine you've got this code:
a = Thread.new {
begin
# do stuff
rescue MyException
end
}
a.raise MyException.new

Is it possible that this will still result in an uncaught exception
within thread a? Thoughts?
Thank you!

Thread#raise is bad, in general, for worse reasons than that:

  t = Thread.new {
    begin
      allocate_resource()
      do_something()
    ensure
      cleanup_resource()
    end
  }
  sleep 1
  t.raise SomeException.new

If the thread is in cleanup when Thread#raise is called, then cleanup
will fail, which is probably not the desired behavior.

There are plenty other examples I've seen as well.
