-//   class AbstractThreadTest    Base class for threading tests.
-//                         Use of this abstract base isolates the part of the
-//                         program that nows how to spin up and control threads
-//                         from the specific stuff being tested, and (hopefully)
-//                         simplifies adding new threading tests for different parts
-//                         of ICU.
-//
-//     Derived classes:    A running test will have exactly one instance of a
-//                         derived class, which will persist for the duration of the
-//                         test and be shared among all of the threads involved in
-//                         the test.
-//
-//                         The constructor will be called in a single-threaded environment,
-//                         and should set up any data that will need to persist for the
-//                         duration.
-//
-//                         runOnce() will be called repeatedly by the working threads of
-//                         the test in the full multi-threaded environment.
-//
-//                         check() will be called periodically in a single threaded
-//                         environment, with the worker threads temporarily suspended between
-//                         between calls to runOnce().  Do consistency checks here.
