**
** The code in this file runs a few multi-threaded test cases using the
** SQLite library. It can be compiled to an executable on unix using the
** following command:
**
**   gcc -O2 threadtest3.c sqlite3.c -ldl -lpthread -lm
**
** Even though threadtest3.c is the only C source code file mentioned on
** Then run the compiled program. The exit status is non-zero if any tests
** the compiler command-line, #include macros are used to pull in additional
** failed (hopefully there is also some output to stdout to clarify what went
** wrong).
** C code files named "tt3_*.c".
**
** There are three parts to the code in this file, in the following order:
** After compiling, run this program with an optional argument telling
** which test to run.  All tests are run if no argument is given.  The
** argument can be a glob pattern to match multiple tests.  Examples:
**
**   1. Code for the SQL aggregate function md5sum() copied from 
**      tclsqlite.c in the SQLite distribution. The names of all the 
**      types and functions in this section begin with "MD5" or "md5".
**        ./a.out                 -- Run all tests
**        ./a.out walthread3      -- Run the "walthread3" test
**
**   2. A set of utility functions that may be used to implement
**      multi-threaded test cases. These are all called by test code
**        ./a.out 'wal*'          -- Run all of the wal* tests
**      via macros that help with error reporting. The macros are defined
**      immediately below this comment.
**        ./a.out --help          -- List all available tests
**
**   3. The test code itself. And a main() routine to drive the test 
**      code.
** The exit status is non-zero if any test fails.
