So the jar's are unpacked into a temporary dir? 

It would be good also to have a solution when fasls are loaded from 
jar directly. It would require to present jar as a file system to lisp, so that
lisp functions merge-pathnames, open and others work on like
#P"jar://some/path/". 

It will solve the with choosing right temporary directory and will
allow to load lisp code in environments where we don't have
writable file system at all - Google App Engine.

Of course, I realize it is probably a significant work of source to support this,
so it's just an idea rather than a "feature request".
