It fixes a number of issues that have been around for a while, plus some others I've recently introduced... Now, I fear this is probably too big a series to be shipped as a fix for 4.3. Can you come up with a minimal series that we could merge quickly (I'm thinking patches 7 and 9), and leave the rest for the following merge window? Thanks, M. -- Jazz is not dead. It just smells funny...
