The proper way to do it is probably to listen for Finder death using a
timeout, not polling the process list.
You can either use the NSWorkspaceDidTerminateApplicationNotification
or use the low level kqueue function which provide such facility.

my goal is to quit an app, check to see if it has quit, and then
relaunch the app if it has quit successfully. i'm sending
quit/relaunch commands with applescripts (tell application "Finder" |
quit | end tell, tell application "Finder | launch | end tell), and
i'm attempting to make this code work without using any type of delay
mechanism but i'm lost.
the following code works very well on quitting and relaunching the
Finder, except if the Finder is busy (copying a file, or something),
the program will continuously try to quit the finder while the finder
prompts that it's busy - it's a continuous loop... a bad scene...
essentially i need to somehow figure out how to have this loop quit
the finder, but stop the loop if it's busy...
