Gets the status for a background job given a job handle. The status information will
specify whether the job is known, whether the job is currently running, and
the percentage completion.

An array containing status information for the job corresponding to the supplied
job handle. The first array element is a boolean indicating whether the job is
even known, the second is a boolean indicating whether the job is still running,
and the third and fourth elements correspond to the numerator and denominator
of the fractional completion percentage, respectively.
