// When we do an update, Mono Paint launches our installer with the /restartPdnOnExit
// flag. This tells us to run Mono Paint when the update is finished. This accomplishes
// two things:
//
// 1. Adds a slight amount of continuity for the user. When they're installing an update
// they'll probably want to start-up Mono Paint right away. So we do it for them.
// 2. Cleans up (deletes) the downloaded setup file. Otherwise, the user has to make sure
// that they immediately re-run Mono Paint under the same user account in order to
// clean this up.
//
// #2 does introduce a slight race condition, so PaintDotNet.exe will actually retry
// up to 3 times to delete the file with a 1 second pause between retries. This should
// give enough time for the setup processes to unwind without causing too horrible of
// a delay in the worst case.
