/* Basic functionality test for tst_fuzzy_sync.h similar to the atomic tests
 * (test15.c). One thread writes to the odd indexes of an array while the
 * other writes to the even. If the threads are not synchronised then they
 * will probably write to the wrong indexes as they share an index variable
 * which they should take it in turns to update.
