This test checks:
- if opening frames/tabs leaks,
- if DrRacket writes to the filesystem during startup or
while opening tabs/frames
- if there are any adjacent separators in the menus
- if there are any duplicate shortcuts in the menus
- that the logger GUI is not completely broken (checks
that it opens, that it catches a GC message, and that
it closes)
