One of my apps uses NSTask to wrap a command line utility that is embedded in the same app’s resources. This utility writes files to disk - I have no knowledge of which APIs it uses to do this. If the task has ended (and I can see that the actual instance of the running command line tool has disappeared from my process tasks in Activity Monitor), and I send the file to the trash, I can’t delete it (empty trash) until the app as a whole is quit - I get the message that the file is still in use.
I’ve checked that I’m closing down the NSTask properly, as far as I can see.
Is this the expected behaviour?
