Yes we turn off consuming data from the pane while it is in copy mode,
so it will fill up the tty buffer and the application (if it has not set
the tty fd to nonblocking) will block.
This is the same as if it was writing to any terminal that doesn't keep
up... applications which don't want to block really shouldn't assume the
terminal will always be able to accept data, because it isn't true. It
is easy to get the same thing in most terminals while selecting/copying
text or by moving things around in the WM.
However, I don't think we really need to stop reading from the pty. I'm
not sure what'll happen if we don't but from a quick look it should be
fine. Please try this and let me know:

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
