== DETAILS

Vagrant has some heinous multithreaded code that depends on
`env[:machine].communicate.wait_for_ready` taking some time to return
so that its threads have time to set their condition variables.

This makes it so that `wait_for_ready` sleeps for 1 second to make
Vagrants threading code happy
