// Common task queues for browser threads. This class holds all the queues
// needed by browser threads. This makes it easy for all browser threads to have
// the same queues. Thic class also provides a Handler to act on the queues from
// any thread.
//
// Instances must be created and destroyed on the same thread as the
// underlying SequenceManager and instances are not allowed to outlive this
// SequenceManager. All methods of this class must be called from the
// associated thread unless noted otherwise. If you need to perform operations
// from a different thread use a Handle instance instead.
//
// Attention: All queues are initially disabled, that is, tasks will not be run
// for them.
