[Numpy-discussion] convert dictionary of arrays into single array

I have a dictionary with structured arrays, keyed by integers 0...n.
There are no other keys in the dictionary.

What is the most efficient way to convert the dictionary of arrays to
a single array?

All the arrays have the same 'headings' and width, but different lengths.

Is there something I can do that would be more efficient than looping
through and using np.concatenate (vstack)?
