[erlang-questions] Binary constantly growing on erlang 18

[Lukas Larsson]

Hello,

Erlang 18.0 seems to have introduced a memory leak in the tty driver for
unix platforms. This means that when printing to stdout the binary usage
will grow. I believe I have found a solution to the problem.

If you have problems with this leak, using -oldshell removes the leak.

Thanks for reporting this issue.
