Damn! Caught with my pants down. I rushed out and ordered a copy
of 1003.4, but probably won't get it for 2 weeks or so. In the meantime,
could you summarize in a paragraph or two, how it requires that
a process may have multiple outstanding requests. Is this really
going to be a problem? It's obvious that a process can only have
a single *sychronous* request pending, and I think these are the ones
that cause the problems.
