[PD] reading arrays from an external

[oscar pablo di liscia]

Many thanks.
So that, if a table is not used in a dsp process, and we
don't use the garray_usedindsp() function,  it is safe to change
its contents providing the fact that this change is properly
done using the access methods available?
