I've got one of these beasts and have noticed that removing a tape at critical 
points in restore will reliably cause the machine to crash (While it's still 
open, just prior to closing & rewinding it). It also calls tsleep from within 
wtintr (actually nested withing a call to wtsense->wtpoll), a definite no-no, 
but wtintr is sometimes called (aaggh!) from the non-interrupt portions of the 
code to do some stuff, so one is never sure if it's legal to do the tsleep.
