not sure exactly how to do it with SDL.

to be fair, that might= not be an ideal solution. QEMU emulation currently requires frequent SIGAL= RM signals.
this means the application will not be able to use it for it= s own needs, and a *lot* of system calls are going to
randomly return EINTR, which a *lot* of code doesn't handle properly (*= cough* *cough* libesd.so)
