The patch allows the testcase to build, but it deadlocks when you run it. The
deadlock is here:
foreach (i in foo)
printf("count of foo[%d] = %d\n", i, @count(foo[i]))
This happens because the 'foreach' opens a readlock on foo, and then '@count'
tries to open a writelock. While this is a valid problem, it may be out of the
scope of this bug.
