Strange error while working on RPC backend

[Derek Atkins]

Here is the server log to show which RPCs get called, and in what
order.  If I try to open it a third time, I get a SEGV in malloc() in
the server.  However, if I kill the server and restart it, then I can
open the file again (and yes, the changes are in the file).

If you have specific questions about operations of these server-side
functions, I can either send you the source for the server (it's
basically one file) or I can answer specific questions.  I tried to
make the functions names relatively indicative of the actual
functionality.
