Update comments and the skip list, maybe some of these tests don't

report failures, we'll see.

Skip certain hopeless tests: compiler and logging.

compiler will likely always show varying leaks since it doesn't work
on a defined set of modules unless -u compiler is specified.  But that
takes forever (we only run with -u network currently).

logging causes hangs when running with -R.
