> There is a need to allow bundles to quiesce gracefully such that in-flight threads in
a replaced module are permitted to run to completion. This could allow updates to be made
to applications without requiring them to be restarted. If a quiesce does not complete within
a suitable time period (e.g. the time a blueprint reference waits), then we should forcefully
stop the bundles! Note that this is not specific to blueprint but anyone that needs to be
aware of the bundle lifecycle.
