As promised, I've put some code with extensive comments that describes
how you could implement locks for your web proxies for those of you
considering multiple processes or threads.  You can find the code in
/mit/6.033/lab/src/other/lock.  In that directory I've put a main
file with two files which show two different ways to implement
locks in UNIX.

If you have any comments, suggestions, or questions, feel free to
email me.
