So, if the spawned +process exits immediately (like in your situation), the file will be +deleted immediately, and even if the viewer sticks around, the file +will be deleted after 30 seconds anyway. + +This must be affecting Gnus users the same way, but I haven't found +any evidence that they're aware of it. The mm-display-external code +still has this problem in both the current Emacs master and the +current Gnus master.
