Sometimes, when I trash something when a long trash-emptying is already happening, a warning alert appears that says the newly trashed file will be directly deleted instead. I wonder if that alert still gets displayed when the trashing is programmatically instigated. That would be a surprise to the user since my program is a command-line tool (which may be called from a script someday).
I would not expect an alert, but I'm just guessing. What I would expect is
an error return. Shouldn't be too hard to create a very large Trash and
and some test code to see what happens in that situation.
