[Bug]: thread 'main' panicked with kind: WouldBlock, message: "Resource temporarily unavailable"

[erszcz]

What did you expect to happen?

First of all, thanks for a great project - (almost) infinite shell history with stats and search is awesome!

I started using atuin yesterday. With Bash integration enabled, when I press the up arrow, I expect the history window to show up, so that I can browse my shell history.

What happened?

The window was printed to screen, but immediately followed with:

thread 'main' panicked at atuin/src/command/client/search/interactive.rs:862:60:
called `Result::unwrap()` on an `Err` value: Os { code: 35, kind: WouldBlock, message: "Resource temporarily unavailable" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

The full shell result that I saw was:

I managed to catch a backtrace with RUST_BACKTRACE=1. Here's a full screen dump showing exactly what happens:

1. I'm in an Elixir shell (actually an Erlang VM).
2. I exit the shell by hitting Ctrl-C twice.
3. Immediately once control is back to Bash I hit the up arrow, to restart the shell.
4. Atuin shows up and crashes.

I think I saw the crash occurring by itself, too, but this time it happened immediately after the Erlang VM exited.

# this printout starts in Elixir shell run in Bash
