Depends... I am not sure whether this will result in clean code
for libfind.

You may have a look at libfind (e.g. from a recent cdrtools
ftp://ftp.berlios.de/pub/cdrecord/alpha/) to see how to do this without the
need to use filedescriptors. A library cannot eat as many fd's as it may like...
I will still have libfind to use an openat() based implementation
in order to support infinite path length in a thread safe way in case the OS
supports openat(). The basic algorithm will stay the same as today.
