Integration tests fail on MacOS with Too many open files (os error 24)

[jedesroches]

Summary

When running the integrationt tests on MacOs, tests start failing with Too many open files (os error 24) errors. It is of course possible to raise the limit via sysctl's and ulimit calls, but it is a bit confusing that tests would fail on a "default" setup...

Reproduction Steps

I tried this:

1. git clone git@github.com:helix-editor/helix
2. (dev shell stuff)
3. cargo integration-test

I expected this to happen:

The tests to be ran.

Instead, this happened:

---- test::commands::surround_replace_ts stdout ----
Error: build signal handler

Caused by:
    Too many open files (os error 24)

Stack backtrace:
[...]

And about 50 similar failures (including the hello world).
