Use a freelist for GDT entries.
...
Tweak the kmalloc space layout a bit. Get the spawn stress test up
and running again.

Way tighter locking in process creation.
...
We no longer disable interrupts around the whole affair.
Since MM manages per-process data structures, this works quite smoothly now.
Only procfs had to be tweaked with an InterruptDisabler.

Allow processes to go into a BeingInspected state (used by procfs.)
...
This ensures that the process won't get scheduled, and so inspecting
it is safe and easy without blocking interrupts.

Preallocate the maximum number of FileHandle pointers (fds) in every process.
...
This could even use a more specific data structure since it doesn't need the
grow/shrink capabilities of a vector.

Move Region and Subregion out of Process and make them free classes.

Process now maps regions immediately when they are allocated.
...
This avoids having to do a separate MM.mapRegionsForTask() pass.
Also, more Task => Process renaming that I apparently hadn't saved yet.
