This might be a limitation of Linux's pty(7) subsystem. The xterm manpage mentions the following: ,---- | BUGS | Large pastes do not work on some systems. This is not a bug in | xterm; it is a bug in the pseudo terminal driver of those systems. | Xterm feeds large pastes to the pty only as fast as the pty will | accept data, but some pty drivers do not return enough information | to know if the write has succeeded. `---- See also https://bugs.debian.org/273194 in xterm.
