+# The test iocmd.tf-32.1 unavoidably exhibits a memory leak.  We are testing
+# the ability of the reflected channel system to react to the situation where
+# the thread in which the driver routines runs exits during driver operations.
+# In this case, thread exit handlers signal back to the owner thread so that the 
+# channel operation does not hang.  There's no way to test this without actually
+# exiting a thread in mid-operation, and that action is unavoidably leaky (which
+# is why [thread::exit] is advised against).

+# Use constraints to skip this test while valgrinding so this expected leak
