I have also found the current CVS code to be on par with my "100% pure
POSIX" recursive file-finder.  The run-times and of the two
implementatoins are identical.

In fact, I even found the Boost.Filesystem implementation to be more
optimal in certain cases since it makes use of the dirent.d_type
member to detect the is_directory-ness of an entry, where my naive
POSIX code was always calling stat(2).  This means fewer syscalls for
the Boost version, which is a win.

Thanks for the great library, Beman!
