are you *really* sure you want to re-source your .bash_profile?  i ask
since it's possible that there are things in that file that really
shouldn't be rerun.

a classic example is to append some entries to your search path:

  PATH=$PATH:blah:woof:.....

rerunning .bash_profile means that those entries will be appended
*again*.  not fatal, of course, but i think too many people very
cavalierly re-source that file without making sure there are no
adverse consequences.
