34 WINS/WINSCW Use X86 locked operations. Assume Pentium or above CPU (CMPXCHG8B available)
35 X86 For Pentium and above use locked operations
36 For 486 use locked operations for 8, 16, 32 bit. For 64 bit must disable interrupts.
37 NOTE: 486 not supported at the moment
38 ARMv4/ARMv5 Must disable interrupts.
39 ARMv6 LDREX/STREX for 8, 16, 32 bit. For 64 bit must disable interrupts (maybe).
