package com.gh.bmd.jrt.runner;
import static com.gh.bmd.jrt.util.TimeDuration.fromUnit;

Class implementing a sequential synchronous runner.

The runner simply runs the executions as soon as they are invoked.
While it is less memory and CPU consuming than the queued implementation, it might greatly increase the depth of the call stack, and blocks execution of the calling thread during delayed executions.
