zsh uses a hash table to store the list of known commands.  When you 
install a new command in your path, you need to update this hashtable by 
invoking "rehash".  This is similar to csh, I believe (been a while 
since I used this last).  bash, on the other hand, does a search for 
valid commands every single time.  zsh provides this possibility, too, 
by setting the "rehash" option, but this is disabled by default because 
it incurs a speed penalty.
