[fireball] 29520: - Fix a long standing bug, which prevented NT to work stable (in fact, it died very soon after booting). The bug was in occasional placing Gdt and Idt into a temporary heap, instead of MemoryData marked area of memory. The possibility of this bug was suggested long time ago by Alex, but I didn't believe him back then :) - Now Windows NT works quite good after booting via WinLdr in QEMU.
