Output is truncated to 2048 byte

[kmyk]

This interpreter cannot print more than 2048 chars.
This behavior may be intended but seems unnatural (at least, undocumented). I want to run programs which print more letters, on this interpreter.
Can I change this? If I make a pull request about this, can you merge it?

I don't have enough time to work on this by myself but I'll sure test and merge!
