Could you tell me briefly what was the source of leak in arccos case?
And how do you write a test code for these cases?

I see your points. I don't want to give you extra work, don't worry :) It just seem a bit bizarre:
I[27]: c.data['Air_Temp'].fill_value O[27]: 999999.99990000005
I[28]: c.data['Air_Temp'][4].fill_value O[28]: 1e+20
As you see, it just returns two different fill_values.
I know, but I hope you see the difference : in the first line, you access the `fill_value` of the array. In the second, you access the `fill_value` of the `masked` constant. Each time you access a masked element of an array with __getitem__, you get the masked constant. We could force the constant to inherit the fill_value of the array that calls __getitem__, but it'd be propagated.
I know eventually you will be the one handling this :) it might be good to add this issue to the tracker.
Go for it, but don't expect anything before the release of 1.4.0 (in the next few months)
This is the last resort. I will eventually try this if I don't any other options left.
I gonna have difficulties fixing something that I don't see broken... Now, there might be something wrong in my installation. I gonna try to install 1.3.0 somwehere. say, what Python are you using ?
OK, I use meld to diff my copy of ma/core.py with the latest trunk version. There are lots of differences :) So there is a possibility that I might have built my local numpy before 09/08. I should renew my copy. Do you know the link of svn browser for the numpy? I don't know how you are making separate installations without overriding other package? I either use Sage (if I have extra time) or SPD. They are both shipped with numpy 1.3.0.
Make yourself a favor and install virtualenv and virtualenvwrapper. That way, several versions of the same package can coexist without interference. Oh, and install pip till you're at it:
