-/* This test checks if concurrent writes to a FILE created with
-   open_memstream are correctly interleaved without loss or corruption
-   of data.  Large number of concurrent fputc operations are used
-   and in the end the bytes written to the memstream buffer are
-   counted to see if they all got recorded.
-
-   This is a regression test to see if the single threaded stdio
-   optimization broke multi-threaded open_memstream usage.  */
