class Garcon::ImmediateExecutor
An executor service which runs all operations on the current thread, blocking as necessary. Operations are performed in the order they are received and no two operations can be performed simultaneously.
This executor service exists mainly for testing an debugging. When used it immediately runs every ‘#post` operation on the current thread, blocking that thread until the operation is complete. This can be very beneficial during testing because it makes all operations deterministic.
@note Intended for use primarily in testing and debugging.
