+Add a single worker process.
 To add multiple workers, use [`addworkers`](@ref).
 
 ## Arguments
 - `env`: Vector of environment variable pairs to set for the worker process.
-- `init_code`: Code use to initialize each worker. This should be used for imports and definitions shared amongst all workers
 - `init_worker_code`: Code use to initialize each worker. This is run only once per worker instead of once per test.
 - `exename`: Custom executable to use for the worker process.
 - `exeflags`: Custom flags to pass to the worker process.
