If a handler's enabled state is configured by a property tester expression (using the selection variable), then, it seems that the tester is polled frequentely. I remember there was a discussion on the e4 dev mailing list: is this behavior to be changed (i.e. just a workaround) or has it gone in 4.4?

Yes that has changed in 4.4 - there's no constant polling anymore. Are
you in a pure e4 application or the compat layer.

Thanks, Tom!
The RCP runs with the compat layer (as it needs IDE features).
