I've been away on a conference last week, so I haven't had much chance to take a look at the code after you integrated it and the test base got increased ;( One thing I discovered are some UP-only deadlocks and the page ping-pong thing, which I am fixing right now. If I had a choice, I'd have chosen /next/ week as the time to integrate the code ... doing this while I'm away at a conference was really inconvenient ;) I'm looking into the email backlog and the bug reports right now (today, tuesday and wednesday I'm at /another/ conferenc and thursday will be the next opportunity). It looks like ther are no fundamental issues left, just a bunch of small thinkos that can be fixed in a (few?) week(s). regards, Rik -- "What you're running that piece of shit Gnome?!?!" -- Miguel de Icaza, UKUUG 2000 http://www.conectiva.com/ http://www.surriel.com/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
