/* NB: timer.device is opened in schedule.c (ultimately by the scheduler process).
* The library base and interface are obtained there, rather than here, due to
* the additional complexities of opening devices, which aren't important here
* (as we only need the library interface), but are important for the scheduler
* (as it also uses the device interface). We trust that the scheduler has
* initialised before any other code requires the timer's library interface
* (this is ensured by waiting for the scheduler to start up) and that it is
* OK to use a child process' timer interface, to avoid opening it twice.
