The LDT _used_ to originally be just a page in size.

It so happens that the only program that I personally think should use
the LDT (ie Wine/WABI) needs _much_ more than 512 entries. Windows is a
segment pig.

I think using the LDT inside threaded programs is a mistake, but if you
do it will still be just one LDT for the whole thread group rather than
one per thread, so as such I'll just keep the LDT to the full size.
