Depends on what you like.  build* or untar-emacs if you like I/O (or just a
grep -r in some tree close to you).  A few getdents-and-unlink* in parallel
is sometimes fun.  I'm not sure what kind of operations are needed, I would
guess just thread intensive things.

I have no idea, and I don't know in what way the generated code may be
different.  Thread things that don't get inlined?  

Was the crash very easy to trigger before?
