Oh, right on-- so I actually don't need to recompile every non-functioning 
threaded package in userland *unless* there is a major version change.  I did 
not know that (and this makes life much, much easier).

So, in essence, if I get a core in e.g. evolution after upgrading libpthread-- 
but without recompiling evolution or its dependencies, I can expect it to have 
already picked up the latest minor version.  Sweet.

Thanks much,
