Keeping a list of what's in a directory is great, as long as you can
guarentee that nothing has changed the directory behind your back.  Think
of how frustrating it would be if a program refused to acknowlege the
existance of a file that you had just created from another window.

This is a worth-while idea; caching a list of file names.  To make it
workable though requires a change to AmigaDOS.  If programs kept a lock
on the directory that the list came from, then all we need is a new
function to tell AmigaDOS to send us a message whenever the directory
changes.  The messsage is a signal to the program to flush its file name
cache.
