On OS X, sage-cleaner never exits because it keeps trying unsuccessfully to delete a directory. Since the directory is still there, sage-cleaner keeps running. It writes a message to the log file every few seconds after trying unsuccessfully to delete the directory, so the log file grows rapidly.
Once this is fixed, sage-cleaner will delete all of the directories, then the log file, then exit. Patch ready for review. I'm marking this as a blocker, since we shouldn't leave any processes running, and it can really pollute the directory .sage/temp of any OS X user. -- John -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
