+ - Fix hangs with collective metadata reads during chunked dataset I/O
+
+ In the parallel library, it was discovered that when a particular
+ sequence of operations following a pattern of:
+
+ "write to chunked dataset" -> "flush file" -> "read from dataset"
+
+ occurred with collective metadata reads enabled, hangs could be
