Following previous discussions on this list and on #lisp, I pushed yet another change to ASDF.
The patch includes better support for system-finding functions, and caching of source-registry data so we only hit the filesystem the first time around. I hope this will make Xach happy. I'll export any symbol he wants supported before the next release, if he asks me.
The patch also handles self-upgrades more correctly. It will only work if the *old* ASDF is 2.014.8 or later, though.
