The timeouts are hooked to the sys_arch_mbox_fetch() and sys_arch_sem_wait()
calls. The stack itself calls wrappers like sys_sem_wait(), there the
timeouts are handled.
The low-level functions that you have to implement must return after
a specified amount of time, or if the semaphore/mailbox has signaled.
The timeout handler will then call the timeout functions as required.

Hope, this helps you
