This is a well known problem with our selection code that cannot be easily fixed. Process filters get to run while responding to selection events, and (alongside the first Emacs instance being under high load in general) can disrupt selection data transfer long enough for the second instance to time out. If the first instance is actually completely hung, then in addition SelectionRequest events will never be read from the keyboard buffer, and it will never get a chance to process selection requests at all. I don't see us ever being able to do anything about that problem.
