Summary: First forward search after recompiling does not work

Initial Comment:
I've integrated forward search as documented, using 
xdvi-search.el with the suggested key bindings and GNU Emacs 
21.2.1, and most of the time, it works fine. 
 
When I recompile the TeX document and immediately thereafter 
perform a forward search (that is, without first activating xdvi), 
the xdvi window is brought to the foreground, but the forward 
search is not performed. If I change back to Emacs and do the 
forward search again, it works. 
 
I think xdvi notices that the DVI file has changed and updates the 
display, but subsequently forgets to perform the forward search, 
as well.

I don't quite know how to test that. There are not many circumstances in 
which the file could not be reloaded. The obvious ones are, of course, 
missing permissions and a corrupted file, which are both handled fine. 
 
The forward search itself also works, of course, in every situation that 
I've tried. Backwards and forwards in the file, with and without changing 
it in between. It handles invalid -sourceposition parameters as well as 
completely garbled files (dd if=/dev/urandom -- you get my meaning) 
 
In short, I can't find any problems.

OK, I tried to fix this in the CVS HEAD, but I'm not 100%
sure that my attempt won't have any bad side effects (e.g.
infinite loops when the DVI file can't be reloaded or some
such). It would be great if you could recompile the CVS HEAD
(try `cvs up -A') and do some testing before I put this into
22.74.1.
