"""Spawn a job into the background.
:Parameters:
- `command`: The command to execute. If it is a string, it will be
parsed for command-line arguments. Otherwise it assumes it is a
sequence of arguments, with the first element being the command to
execute.
If the command does not contain a slash (/) it will search the PATH
environment for the executable.
- `stdin`: Either `DEV_NULL` or `PIPE`.
- `stdout`: Either `DEV_NULL` or `PIPE`.
- `stderr`: Either `DEV_NULL`, `PIPE`, or `STDOUT`.
- `fd_except`: A list of file descriptors to NOT close. By default all
file descriptors (except for stdin/stdout/stderr are closed).
- `cwd`: The working directory to use for the child process (the
default is to leave it alone).
- `env`: The environment to use. If None, the environment is not
changed. May be a dictionary or a list of 'NAME=VALUE' strings.
- `pgrp`: Set to -1 to keep process group unchanged, 0 to create a new
job (default) and >0 to set process group to pgrp
:Return:
Returns a `CoroProcess` instance.
:Exceptions:
- `OSError`: General low-level error.
- `ValueError`: The command value is invalid.
