Hmm, I don't like the fact that it displays a "stray" entry for each
IRQ.  Perhaps it should skip stray entries unless the count is
non-zero or a different option (-A perhaps) was specified.

Also, why do I get a ??? entry at the top of the list?

des@dwp /usr/src/usr.bin/vmstat% vmstat -ai
interrupt                          total       rate
???                                    0          0
irq1: atkbd0                       76236          0
stray irq1                             0          0
irq3: sio1                             1          0
stray irq3                             0          0
