Add close-on-exec flag for file descriptors.
...
I was surprised to find that dup()'ed fds don't share the close-on-exec flag.
That means it has to be stored separately from the FileDescriptor object.

Add primitive FIFO and hook it up to sys$pipe().
...
It's now possible to do this in bash:
cat kernel.map | fgrep List
This is very cool! :^)

Fix some paging related bugs exposed by the spawn stress test.
...
- Process::exec() needs to restore the original paging scope when called
on a non-current process.
- Add missing InterruptDisabler guards around g_processes access.
- Only flush the TLB when modifying the active page tables.

The colonel task already had a halt loop.
...
Also don't reap() current in the scheduler, just wait until it's not current.

Get rid of the undertaker and have waitpid() be the reaper.
...
For dead orphans, the scheduler calls reap().

Move the scheduler code to its own class.
...
This is very mechanical.
