Rewrite a c version. Per out customer's test, still see concurrency.

@ $ gcc -Wall -O3 -m32 -march=i686 futexCase1_r1.c -o futexCase1_r1 -lpthread
@ -D_GNU_SOURCE
@ $ ./futexCase1_r1
@ 8279: created mutex: 0xf7f1a000
@ 8419: pthread_mutex_consistent_np failed: 0xf7f1a000 22 Invalid argument
@ 8438: pthread_mutex_consistent_np failed: 0xf7f1a000 22 Invalid argument
@ 8439: pthread_mutex_consistent_np failed: 0xf7f1a000 22 Invalid argument
@ …
@ 8279: Done! lock concurrency: 0, max: 7
