Since I don't want to release wsgix under GPL, I'm thinking to release 
flatpages as a separate package.

But I would really like if the core Mercurial API can be released under 
a BSD like licence.

By core API I mean the modules revlog, changelog, filelog, manifest, 
transaction and lock.

Is this possible?

Another legal question/curiosity: is it possible to release the main 
framework under a BSD like licence and one of the subpackages under GPL?
As I have said, the hgrepo module is used only inside the flatpages 
package, and the flatpages package is not used by any other part of wsgix.

I know the question very well, and this is the reason why I try to avoid 
GPL for my libraries.
