Co-arrays?

One more question on my inventory list:  When will gfortran support
co-arrays? (Where's it fall on the to-do list?)

As I've mentioned in previous postings, I was in the process of
translating a large piece of C++ code (~15,000 semicolons as such
things are measured).  It was pretty much a line by line translation,
with the exception that I replaced C++ loops with Fortran vector
statements when possible.  When done I got ~15% better performance
using Fortran vs. C++ (gfortran vs g++).

My contractor asked for other avenues using Fortran to improve
performance and, of course, this brought up co-arrays.
