Emacs leaks memory as lines are printed in a shell buffer.  Here is a
recipe:

    emacs -Q
    M-x shell
    yes "This should not leak, but it does."

Observe the memory usage grow in a tool like “top”.  Once you decide
that Emacs has eaten enough memory, kill the shell buffer.  Note that
memory is not released.

This is a problem for me because I often compile software in shell
buffers (via “guix build”).  The compilation processes often print out
very large amounts of text and Emacs quickly eats up all memory on my
machine, freezing it.  I can only recover from this by killing Emacs
(which is terrible, because I live in Emacs).

This has not been a problem in Emacs 24.x; I’m also pretty confident
that this was no problem in version 25.1.
