==========

A thread and exception safe implementation of lazy (aka on-demand) value

initialization.

Features:

- Initialization is guaranteed to run only once in multi-threaded scenarios

  as well in case of raised exceptions

- The initializer is released after initialization so it can be collected by

  the garbage collector. This is still true if initialization fails.

- Exception raised during initialization are propagated in the same thread

  (this is important if a `InterruptedException` for that thread is raised

  during initialization)

- Exceptions raised during initialization are kept for later inspection/logging
