Unfortunately, in the threads branch this file hangs -- though the test 
it hangs on may differ from run to run.

Below:  the file hangs at test 37.

$ prove -v t/pmc/nci.t

But on the next run, I got through test 37, only to experience a hang on 
test 38:

ok 37 - nci_cb_C1 - PASM

And on the third run, I got through both 37 and 38, only to hang on 39:

ok 37 - nci_cb_C1 - PASM
ok 38 - nci_cb_C1 - PIR

But on the fourth run, I was back to hanging on 37.
