Well, after a quick look through appmgr/global.c I isolated the memory leak to the
panel's app_info structure. When an application is registered, an app_info structure
is saved with the registration info such as its name, owner, type, and widget. This
structure is freed on app exit, but not when the app is explicitly deleted or put out
of context, therefore causing exactly 1 allocation (but no handles) to leak per
open/close cycle of that panel test I posted.
I'll fix this soon... Just need to have the widget delete function check for an
app_info node if it's a root widget

Only wimps use tape backup: _real_ men just upload
