And I just found that after I kill opal_lifo, the opal_fifo test hangs too.
Output was not shown by "make check", but here is what I see manually:
$ ./test/class/opal_lifo
Single thread test. Time: 0 s 35084 us 35 nsec/poppush
Atomics thread finished. Time: 0 s 197821 us 197 nsec/poppush
^C
$ ./test/class/opal_fifo
Single thread test. Time: 0 s 47514 us 47 nsec/poppush
Atomics thread finished. Time: 0 s 142369 us 142 nsec/poppush
^C
Sorry, no backtrace for opal_fifo because I have to head to a meeting now.
