Description
@lzrd just had to bump the stack size on the gimletlet/app-mgmt demo's net task to 3328 bytes. That's quite a bit larger than I would naively expect. This issue is a reminder to look into what data net is keeping on the stack, and see if we can move it into statics where it's more easily accounted for.

Research direction
Start with the net task in the gimletlet/app-mgmt demo and inspect which data it keeps on the stack. Done means identifying the stack usage and, where appropriate, moving data into statics so the task needs less stack and its memory use is easier to account for.
