Add tcsetpgrp()+tcgetpgrp().
One more step on the path to being able to ^C a runaway process. :^)

Free physical pages allocated for a process's page directory on exit.
Also use a ProcessPagingScope instead of region aliasing to implement
create-process ELF loading.

and running again.

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.

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.
