Interface for walking a job tree.
Public Methods
zx_status_t OnJob (int depth, zx_handle_t job, zx_koid_t koid, zx_koid_t parent_koid)Each of these methods visits the corresponding task type. If any On*()
method returns a value other than ZX_OK, the enumeration stops. See
|task_callback_t| for a description of parameters.

remove this function.

bool has_on_job ()Subclasses must overload these to indicate which task types to actually
visit. Avoids, e.g., visiting every thread in the system when a caller
only cares about jobs.
