Does not work for me, error message on OpenBSD/amd64:
Could not allocate dynamic translator buffer
ktrace snippet:
74960 qemu-system-spar CALL mmap(0,0x40000000,0x7<PROT_READ|PROT_WRITE|PROT_EX
EC>,0x1002<MAP_PRIVATE|MAP_ANON>,-1,0)
74960 qemu-system-spar RET mmap -1 errno 91 Not supported
It's doing a RWX mapping, won't fly on OpenBSD.
