* Sleep for the specified amount of time.
* This call will block for at most the specified amount of time. It allows epicardium to
* reduce clock speed of the system until this call is finished.
* This call returns early if an interrupt is signaled from epicardium.
* The clock source of epicardium has a limited amount of accuracy. Tolerances
* of +- 10% have been observed. This means that the sleep time also has a
* tolarance of at least +- 10%. The exact amount varies from device to device and
* also with temperature. You should take this into consideration when selecting
* the time you want to sleep.
* :param ms: Time to wait in milliseconds
* :returns: 0 if no interrupt happened, ``INT_MAX`` if an interrupt happened and the sleep ended early.
