my $job = TAP::Parser::Scheduler::Job->new( $filename, $description );
Register a closure to be called when this job is destroyed. The callback will be passed the "TAP::Parser::Scheduler::Job" object as it's only argument.
$self->filename; $self->description; $self->context;
These are all ``getters'' which return the data set for these attributes during object construction.
For backwards compatibility in callbacks.
Returns false indicating that this is a real job rather than a 'spinner'. Spinners are returned when the scheduler still has pending jobs but can't (because of locking) return one right now.
