oops. scheduler() inherits the interrupt status of the
...
most recent process to run, so it must explicitly
turn them on again. It would be better if cpu->intena
were really thread->intena.

Separate tests in slow and quick. The slow tests run xv6 out of

memory, out of disk space, or test big directories.
Support -q option to run only the quick tests, which saves about
7mins.

Experiment with being more precise setting permissions for user pages.
...
Growing adds R|W pages (without X). Exec() marks the stack only R|W.
Probably could setup permissions for text and data better if we call
ld with --no-omagic instead of -N.
