Granted, I reversed the order of the arguments for seek().  But killing the
interpreter is a bit harsh.  This happens on all irix systems I was able to
test.  Linux just ignores the bad SEEK_* arg.  I don't know if this is because
it doesn't send SIGSYS for that, or because linux python is catching it.
The hpux and solaris boxes are down so I couldn't test them...

Anyone else on irix see this?
