I haven't personally done any testing with the maskedarray branch 
myself, though I know Eric Firing has done a little.

This seems to work if you change it to npy.compress -- for both the 
"default" ma and the maskedarray branch.  I'll go ahead and commit this 
change, though there may be performance implications.
