// TEST PLAN
//-----------------------------------------------------------------------------
// Overview
// --------
// The basic idea of testing bslmt::QLock and bslmt::QLock is to create thread
// poll and manipulate various test data in parallel, then to check that the
// integrity of data is preserved.
//
// The helper class MyTask provides thread pool and its management. This class
// creates thread pool, executes in each thread specified function and join all
// threads to make sure that there are no unfinished threads left and there is
// no leak of resources. The class also is a convenient place holder to common
// data used by thread function.
//
// The helper class Rand provides generation of pseudo-random numbers for each
// thread.
//-----------------------------------------------------------------------------
// CLASS bslmt::QLock CLASS bslmt::QLockGuard
// [ 5] Contention test: many threads - many bslmt::QLocks
// [ 4] Test of internal QLock core primitives:
// setFlag and waitOnFlag
// [ 3] Aggressive contention test: many threads - one bslmt::QLock
// [ 2] USAGE EXAMPLE: MT-Safe Singleton.
// Design is based on combination of bsls::AtomicInt
// and bslmt_QLocks.
// [ 1] BREATHING TEST
