Not surprising as this is a shared memory driver specific question.
It supports using either interrupts between the boards or installing a
routine that is called on each clock tick to poll for new packets.
This is configurable on a per BSP basis via the shmconfig support.

[NOTE: The shared memory driver predates the Classic API timer
manager.  It really should use the timer manager for its polling
routine instead of the clock tick trick it is currently using.]
