lord of the caches: fellowship of the exe cache file. how to get what is most
likely an up-to-date list of all executables in $PATH as fast as possible and then in the background build a new list from files and if this list does not match the cached list once built, throw away the old cache file and write out a new one. :) this should be about the best of all worlds - instaant exebuf appearance and storing previously discovered info as well as never hanging "solid". there is a chance the data you have is incomplete or out of date - but thats better than the wm just hanging there for 10 seconds while disk IO thrashes.
