Greg, here are things that I think will make mixed-code reasonably common.
* Using the native Java interface along side an OS library
* different 64-bit and 32-bit libraries
* Using Heimdal and MIT code on the same system
I think the standard we want is to try and avoid increasing the false
positive rate over what it is today.
