Would it make sense on the i386 port not to use a GDT slot for a process
which is not running or runnable?  If the TSS and LDT base slots are
only used while the process is in the run state (and yielded when the
process sleeps), we could theoretically support more processes.
Complexity?  Performance impact of reloading GDT slots?  I don't know
offhand...
