** This test program runs on unix-like systems only.  It uses pthreads.
** To compile:
**
**     gcc -g -Wall -I. threadtest4.c sqlite3.c -ldl -lpthread
**
** To run:
**
**     ./a.out 10

** The argument is the number of threads.  There are also options, such
** as -wal and -multithread and -serialized.
**
** Consider also compiling with clang instead of gcc and adding the
** -fsanitize=thread option.
