63 The use of threaded interrupts is the most likely condition to trigger
64 this problem today. Threaded interrupts may not be re-enabled after the IRQ
65 handler wakes. These "one shot" conditions mean that the threaded interrupt
66 needs to keep the interrupt line masked until the threaded handler has run.
