Providing the msvcrt module used by getpass in Jython would be more  
involved than just installing a dll, we would need a JNA interface to  
its API. And of course POSIX handles getpass differently.

However Java 6's java.io.Console does provide a safe password reader,  
so implementing a java_getpass with it would be the simplest solution.  
We may require Java 6 for Jython 2.6, but regardless this could be  
included in 2.5.1 with a fallback to the unsafe version on Java 5. It  
should be a fairly simple addition to getpass.py if you want to take a  
crack at it.
