Scheduler

trait Scheduler[T <: Txn[T]]

A Scheduler uses a logical frame clock to execute functions transactionally at specific times. It is parametrized in S in order to perform transactions, but it does not store any state that would need the scheduler to be handled with stm.Source. It can be safely stored in a regular value.
