-mask interrupts w/o a handler
...
-update PIC _after_ the interrupt handler is linked into the chain
This fixes problems with dynamically installed interrupt handlers:
Interrupts were enabled before the handler was installed under some
circumstances (esp. on faster machines), leading to endless interrupt
handling.
