Also, does the latency test run on your platform? Because if it does, it
shows that the bug is elsewhere: latency contains a call to mlockall and
registers a signal handler for SIGXCPU.
And if you want us to help you, you should tell us what happens if you
do not comment mlockall, because we can not guess it. See, we run
latency all the time, and obviously, we have no issue.
