It is more likely that the cause of a slow rake startup is the time it 
takes to calculate any filelists used for dependency detection.  For 
example, the filelist used for the clean target searches your entire 
project tree looking for files that can be deleted.  An obvious 
optimization would be to delay the creation of a filelist until we 
really need it.

If slow startups are a problem, I'll look into some possible fixes.
