Skip is right. When trying to find out why the hgprompt extension (which 
is a rather nifty extension adding color-coded repository information 
into your bash prompt) made the shell so much slower, it turned out that 
most of the execution time comes from importing *Mercurial* modules, not 
stdlib modules.
