// This file implements a simple standalone program used to test whether
// or not the SQLite library is threadsafe.
//
// Testing the thread safety of SQLite is difficult because there are very
// few places in the code that are even potentially unsafe, and those
// places execute for very short periods of time.  So even if the library
// is compiled with its mutexes disabled, it is likely to work correctly
// in a multi-threaded program most of the time.
//
// This file is NOT part of the standard SQLite library.  It is used for
// testing only.
