Multi-segment background application

[Gary]

I have a background application, which has no UI whatsoever, that has
unfortunately grown beyond the 64K segment limit. I need to figure out
some way to call code accross segments, without being launched with
sysAppLaunchCmdNormalLaunch. Specifically, I need to find a way to
launch myself with globals, and not trigger any UI at all (i.e.
SysAppUISwitch is not an option). I'm using Codewarrior 9.3, and
targetting PalmOS 5.4, specifically the Treo 650.

Here's what I understand:

- You cannot call anything out of your first segment on a no-globals
launch.
- The above is true, no matter what magic you use in Codewarrior (e.g.
expanded mode doesn't help).
- You cannot call yourself using SysAppLaunch and pass
sysAppLaunchFlagNewGlobals, as that will eat up an owner ID every time
you do it.

So, do I have any options at all here? Is there any way to get my app
launched in a context where I can call other segments, short of
SysAppUISwitch? Surely there is a way to do this.

Thanks,
Gary
