-/** @class ExceptionStore
- * @brief A parent class for classes which have a need to catch and
- * re-throw exceptions.
- *
- * This is intended for classes which run their own thread; they should do
- * something like
- *
- * void my_thread ()
- * try {
- * // do things which might throw exceptions
- * } catch (...) {
- * store_current ();
- * }
- *
- * and then in another thread call rethrow(). If any
- * exception was thrown by my_thread it will be stored by
- * store_current() and then rethrow() will re-throw it where
- * it can be handled.
