Freezes on :x on large file

[rgoulter]

Summary

When using helix to open large files (> 1.0MiB), when I try to run :x or :wq the editor hangs.

Using :w :q instead behaves as I'd expect.

Reproduction Steps

I tried this:

• For a big file, I was using ~/.local/share/fish/fish_history. But using e.g. plaintext from gutenberg https://www.gutenberg.org/ebooks/1342

wget https://www.gutenberg.org/files/1342/1342-0.txt -O pnp.txt
cat pnp.txt pnp.txt > pnp2.txt
du -sh pnp2.txt

1. open with hx pnp2.txt

2. invoke command :x.

I expected this to happen:

The editor to quit. I expect that wq should behave the same as :w :q.

Instead, this happened:

The editor is unresponsive, and looks as it does before <Enter> is hit.
