Summary: DirectoryScanner extremely slow

Initial Comment:
I have a FileSet which is quite large (see below). nant 
takes about 40 seconds on my machine to Scan() the 
FileSet. Ant just takes about a single second for the 
same set. 

The 'funny' thing is that the time to create the fileset 
(until the message 'Compiling XXX files' appears) takes 
about 40 seconds, the actual compilation is then done in 
about 5 seconds.

Perhaps my FileSet is a bit exotic (there are about 800 
*.cs files below ext/swt30 and the FileSet selects about 
500 out of the 800):
