On Mac Rosetta emulates via LDT plus 32-bit CS (which is pretty much what WOW64 does)

Haven't looked into ARM - I am pretty sure it's a JIT approach.

We need people looking into whatever mess I did with Wine %gs/thread-SIG handling. So feel free to have a look, people are already finding some nice bugs and fixing them.

Nice to see people interested
