Great, now I'm up to date with SVN.

And I can let it be known that, with these changes, I've had no problems 
with mod_mono for many months under ~50k pageviews per day.

There is still some issue on httpd start (emitting right to the console 
and not to the error log):

File exists: Failed to create shared memory segment for backend '...' at 

It doesn't seem to actually cause any problems, but it is very strange. 
The named file does not exist when Apache starts, and trying to unlink 
it right before the call that's causing that error doesn't do any good. 
It nevertheless complains about the file existing.
