bug report: array resize

[Larry Troxler]

I've had instances of segmentation faults when resizing an array.

I suspect this happens when an array is downsized  while a tabread4~
object is running, resulting in newly invalid refrences when the
tabread4~ runs its next slice. 

I must admit to not not having narrowed this down with test cases, but a
quick scan of the code shows no evidence that this situation is not
handled. If I'm wrong I'll buy a beer ...

And of course, this is only a minor bug if the cause is known, because
the workaround is easy, just turn off dsp before resizing, which in most
cases is the only thing that makes sense anyway.
