tcsh builds a hash of all commands so that it can search quickly.
Fortunately, it's clever enough to see when a file disappears and to then
look for another version farther down the path, but it won't find a new
program unless you type "rehash" to rebuild it (or source your .cshrc,
which has all sorts of other problems but people love to do it anyway).

I can only figure that bash doesn't have such a hash table.  Given a path
setting of $PATH without executable 'x' in it, can you drop 'x' into
place and just run it or do you have to tell bash something like

  PATH=3D$PATH

(which I seem to recall having had to do under UNIX with 2.05a in such a
situation, but I could be wrong) to get it to take a look again?
