I don't think it is possible. I also think that the performance sensitive parts
shouldn't have anything to do with PyQt in the first place. We use Pyrex
exactly for this purpose, but the parts we optimize are far far far from the
package which imports and uses PyQt. I'm failry positive that, even if your
application is not well decoupled, you can still isolate the performance
sensitive algorithms in functions which have nothing to do with PyQt.
