Concerning naming of shared memories I went one step further due to some requirement of a local experiment. 
The experiment needs to change the experiment name shown on the web status page depending on the exact 
configuration, but we do not want to change the whole midas experiment each time.

So I simple removed the check that the experiment name coming from the environment and used for the shared 
memory gets checked against the experiment name in the ODB. The only connection there is that the ODB name 
gets set to the environment name is it does not exist or is empty, just to have some default value. So for 
most people nothing should change. If one changes however the name in the ODB (under /Experiment/Name), 
nothing will change internally, just the web display via mhttpd changes its title.

I hope this has no bad side-effects, so please have a look if you see any issue in your experiment.
