Since the interrupt generator is now spawned right after the hooks task and the generator can generate interrupts whenever it wants, it's possible for an interrupt to fire before task switching is enabled. When this happens, the main thread needs to be suspended so that the IRQ can be serviced. BRANCH=None BUG=None TEST="make clobber && make -j buildall tests" several times."
