At this point in the x86 boot process, exec has enabled interrupts/multitasking internally, however we do not yet know enough about the system to have a scheduling heartbeat. This means we must co-operatively yield CPU time to let the ACPICA Init task run and finish configuring the ACPI environment so that we can determine what hardware features are available to configure the interrupt controllers, at which point we will enable the real heartbeat and bring pre-emption online.
