Possible memory bloat because of process runner output buffer

[steezeburger]

Clear the buffer sometimes or use a circular buffer or something probably

Might be able to clear safebuffer after every write, similar to how tview's AnsiWriter works.

This along with the feature that writes logs to disk should be sufficient for a good dx with no memory bloat.

• so the TextView has a buffer that only gets cleared if max lines is set,
• AnsiWriter has a buffer that gets cleared every time it writes
• SafeBuffer has a buffer that never gets cleared
  i think we could clear SafeBuffer after every write though, since we're keeping all the text in the TextView buffer at the moment
