Any issues with incremental compilation? Disabling it may slow CI.

The debug flag semantics are a bit confusing - when debug: true, terminal output is suppressed (only goes to logs). Intuitively, I'd expect --debug to mean "show more output", not less.

Could you clarify the intent here? If the purpose is "redirect output to logs only when in debug mode", would a name like log_only or suppress_terminal be clearer?

Suggested change

	if !self.debug {
	(&self.raw_term).write(buf)?;
	}
	debug!("{}", String::from_utf8_lossy(buf).trim());
	Ok(buf.len())
	let written = if !self.debug {
	(&self.raw_term).write(buf)?
	} else {
	buf.len()
	};
	debug!("{}", String::from_utf8_lossy(&buf[..written]).trim());
	Ok(written)

The Write trait contract states that write() returns the number of bytes actually written.
