    A new monitor which first handles the exception with this, then passes it onto next unconditionally. The new monitor handles the exception if either this or next does.

  5. def apply(f: ⇒ Unit): Unit

    Run f inside of the monitor context.

    Run f inside of the monitor context. If f throws an exception - directly or not - it is handled by this monitor.
