 # Tests that are broken with GC stress.
 # * 137-cfi needs to unwind a second forked process. We're using a primitive sleep to wait till we
 #   hope the second process got into the expected state. The slowness of gcstress makes this bad.
-# * 961-default-iface-resolution-generated is a very long test that often will take more than the
-#   timeout to run when gcstress is enabled. This is because gcstress slows down allocations
