Is there a general solution to the case of read() being called minimum
twice for a file in /proc? I have a small file in /proc, whose data takes
a fair time to generate. My read() handler gets called once for the data,
and once so I can return 0 to terminate read().

This results in the actual read taking twice as long. Perhaps I am missing
something...
