[omniORB] Starting omninames with -start option

No.  It reads the log file into memory if it exists and you don't use
"-start".  Then it appends to the end everytime there is a transaction
that modifies the naming tree.  Periodically, it checkpoints (renames
..log -> .bak and creates a new .log, etc.).  That doesn't sound much
like overwriting.  I'm not sure where the TRUNC option comes into play.
I'm guessing it is only used during check pointing to create a new
*.log file from scratch (which would actually be the *.chk (sp?) file
which eventually is renamed to *.log).

You can certainly start it as a windows service.  Just take the
"-start" option off.  You really don't want to do that unless
there's a problem.  If you do you will loose all of your
contexts.  The whole point of maintaining the *.log and *.bak
files is that you want these contexts to "persist" between
incarnations of the server.

It might be nice not to have to run omniNames with -start the first
time (i.e., have a -start-if-needed or something). But then again,
I kind of like having the sanity check that the *.log file should
always exist under normal operation.
