Good idea! I implemented it and it reduced the number of cache 
files/directories in the tree from 633 to 26. The only drawback is that 
if the script is interrupted whilst checking a sequence of files with 
equal mtime, it will have to start over with that sequence the next time 
it is executed. (Files often get the same mtime if they are edited in an 
IDE and then all saved when executing the build command.) But reducing 
the number of cache files is worth that minor inconvenience.

In case anyone is curious, the script is here:
