Can alarms be used in userspace? I ask because the docs still say RTDM
timers can be used in userspace but Gilles told me they can not be.
Also, does the alarm run at the priority of the thread that created it
or does it run at a priority higher than anything else?

In case of doubts, the best documentation is the header: check in
include/native/alarm.h if the function you want to use is available in
user-space.
RTDM is special, because it only exists in kernel-space.
