CTRL+X sometimes crashes on Linux

[Emik03]

Version

C# REPL 0.6.6+ba21d409af4dce77f8be07f6a61cdb24cd19bb29

What happened?

Clearing the clipboard made it stop crashing, possibly related to #325, but having 🏴󠁧󠁢󠁥󠁮󠁧󠁿 in the clipboard, or arbitrary large text doesn't seem to annoy it in any capacity.

The keystrokes leading to the crash are: csharprepl --trace, ENTER, CTRL+X.

❯ csharprepl --trace

Appears to be due to a hard-coded 500ms timeout in the underlying TextCopy package: https://github.com/CopyText/TextCopy/blob/701c64408f75a7a5a8f4b0328372aca643a69c06/src/TextCopy/BashRunner.cs#L48
