Revisting the local-file-fetching hang

Even with the latest cvs source, I continue to experience a problem
with lib-www hanging when fetching nested local files.  If you want
to see the hang in action, run webbot with a depth of at least 2.
For example:

% cd ~/src/libwww
% webbot -depth 2 -prefix file:$PWD file:$PWD/Library/src/HTCache.html

It should fetch 23 documents, however it stops after about 7 (with 6
outstanding requests) and infinite loops.

If I apply the age-old fix from Kinuko Yasuda, however, it works
fine.  I have not attempted to look into the details of what is
going on here, though, so is there a reason that this fix has not
been committed?  Is it not quite right somehow?
