-******************************************************************************
-**
-** This file presents a simple cross-platform threading interface for
-** use internally by SQLite.
-**
-** A "thread" can be created using sqlite3ThreadCreate().  This thread
-** runs independently of its creator until it is joined using
-** sqlite3ThreadJoin(), at which point it terminates.
-**
-** Threads do not have to be real.  It could be that the work of the
-** "thread" is done by the main thread at either the sqlite3ThreadCreate()
-** or sqlite3ThreadJoin() call.  This is, in fact, what happens in
-** single threaded systems.  Nothing in SQLite requires multiple threads.
-** This interface exists so that applications that want to take advantage
-** of multiple cores can do so, while also allowing applications to stay
-** single-threaded if desired.
