I also use system enhancement utilities on the Treo, these are really Palm OS specific. In fact, I am using handheld devices since mid 90', and all of them needed a handful of utilities to fill the gaps of the system.

Maybe these can help to prevent the crashes of the Garnet VM, too. Because the Treo really needs these to function smoothly. Many of these apps are written by the same person (HobbyistSoftware), who knows the Palm OS deeply, and corrected all the shortcumings that Palm/Access should have done.
