1f5d311ca1 - fixed memory leaks found with valgrind when trying to start a second 
simulation with wxBochs:

3ab94305a0 1. Fixed bug report 
[ bochs-Bugs-1562172 ] TLB_init() fails to initialize priv_check array if USE_TLB 0

   To disable paging it is better to use normal model without special code, only by setting cr0.pg=0
