bug#49253: 27.2; Emacs non-responsive when pasting into terminal-mode

[Matt Bisson]

This is the Mac Terminal application that comes out of the box with
MacOS.  It fully supports xterm-256color as the TERM type, and I can
actually paste just fine in other parts of Emacs.  Although I'm having
trouble getting to a Linux terminal emulator these days, I realized
that I do have a machine running WIndows.  I ran the Cygwin terminal
emulator, MinTTY, started (terminal, Cygwin -- i.e., not the Win32
native) Emacs, and it exhibits the same behavior.  Something more
fundamental seems to be going wrong.
