Aha!  The problem isn't that curproc is garbage, but rather that it's
being interpreted wrong.

struct proc has some extra fields when KSE is #defined.  KSE recently
became a kernel option and was put in the DEFAULTS file, so everyone's
kernel has it defined.  But kqemu is being compiled without it.

I compiled with -DKSE and now kqemu works!

This seems like it would be a common problem for modules compiled
outside the kernel tree.  Is there an established way to get the
standard configuration options?

I'm thinking also about other options like SMP, that for instance
changes the way mutexes work.
