Keep in mind that every file rename invalidates outstanding patch sets against 
those files maintained in our own branches, and at external vendors.  I think 
we should be cautious about gratuitous renaming, as it increases the work 
factor both inside and outside the project significantly for relatively little 
gain.  Especially when the files already have a quite consistent naming scheme 
that makes it easy to know which files belong to which component -- tcp_*, 
sctp_*, udp_*, etc.
