Something like this:

tail -f /var/www/apache/access.log /var/www/apache/error.log

The problem with that approach is really long lines wrap and I usually just care about the far left of the file, so I’ve been looking for a way to turn off wrapping in tail. Unfortunately that seems to be impossible. I tried messing with my shell to kill the extra characters with this:

echo -e "\e[?7l\c"

But that was messing up other things. The best solution I’ve found so far is to use less with these options

less +F -S /var/log/apache/access.log

+F puts it in a tail like mode and -S chops the line to the screen width, the only drawback is that it doesn’t intersperse the 2 files like tail does. I was hoping to pipe tails input into less in the this fashion but that didn’t seem to work right either.

To kill it quickly on a Mac you can do the following from a terminal:

ps -A | grep adl


That will return a line that looks something like this

18132 ?? S 0:22.97 /Users/joshbloom/Applications/flexb_183522/Adobe Flex Builder 3/sdks/3.0.0/bin/adl -runtime /Users/joshbloom/Appl
18148 p1 S+ 0:00.00 grep adl

The number at the beginning of the first line first line indicates the process ID of your unresponsive AIR app.

To kill it you would run this command:

kill -9 18132


Be careful what number you put into the kill command, it will happily kill anything you tell it to. If you make a mistake you may have killed your window manager, your instant messenger or even something important like your twitter client.
