Well the base squeak vm and image have no way to change the  
permissions on a file. So

(a) you have an FFI call that does that?
(b) I have painfully discovered in the past if you exceed the disk  
full threshold which is not 100% btw then writes to the disk will  
fail, so is your hard disk *nearly* full? I
believe it's a percentage of the total size, not a fixed value.
(c) I'm not sure if you exceed a certain size for the changes file if  
it becomes an issue.
