it will last till the string snaps. racket at this condition will probably not survive another re-string. use it for light hitting or lend it to friends.
I suggest applying a drop of supa glue to the crack...did it to my racket and it lasted ever since; also when the string breaks, consider stringing at not more than 22lbs; hopefully it works for you as well
yea i applyed some loctite superglue on the crack, I am going to use this racket just for defense and netplay. @22lbs
