The problem with the current "merging" is that it's extremely hard to figure out whether some code in x86_64 might be using some code in i386 since there are currently 5 (five) different mechanisms used for sharing code between the two architectures. It happens so often that someone accidentally breaks one architecture because he didn't notice the code also gets used on the other architecture. > -Andi cu Adrian -- "Is there not promise of rain?"
