Sorry about that.

I understood this differently than what you were asking :).  Wrapping 
and "magic module" objects are  sub-optimal for situations like this; 
best is to import it only when needed so you get an ImportError if and 
only if you try to invoke the functionality that requires pwd on a 
platform that doesn't have it.

This should probably be in the coding standard someplace.

We _also_ need a test farm set up so we can tell when people do this 
:-).  I really need to specify what kind of code needs to work in 
Jython; I'm pretty sure I saw some patches recently that moved errno 
imports around so that Jython will now fail to run twistd or mktap.

That would be best, thanks.
