Fix non-deterministic test pause_by_space

There was no sleep between unpause and exit, causing a race condition on some
terminal emulators, which is the root cause of random CI failures on Windows.

However, it's important to note that the "failure case" we saw on Windows is
actually the correct expected case of the test. On Linux and MacOS, the race
always resolves one way, causing the unpause event to be in practise untested.

To fix it, I simply made sure events are always separated by sleeps.
