Summary: dircache fix; raise like os.listdir, plus optimization

Initial Comment:
I think it would be better if dircache.listdir acts
like os.listdir on missing 
directories; raise os.error

Additionally, I rewrote the logic so it's about 15%
faster.  If you remove 
the outer try-except-block which purges the cache for a
folder on a 
miss it's 30% faster. This makes if five times as fast
as os.listdir (with
my program).

Not sure if anybody cares about the speed, the thing I
was surprised
about was that dircache wasn't a drop-in replacement
for listdir.
