put url some url into someVar: nasty crash :(

[david bovill]

My script keeps crashing Rev... and I think it is a simple as this line:

      put url ("file:" & someFile) into someData

But if the file is big enough - in my case a 900MB video file (or  
anything larger) - instant crash. No graceful wait for virtual memory  
to kick in :( This is OSX with 1GB memory - not OS9! Can this be right?

Can't think of any other way of doing what i need - using the md5Hash  
function to uniquely identify the video files and associated text  
files. Is this a problem on Linux and Windows?
