Leginon

Newer mysql appears to default not to autocommit but to wait for transaction to finish or when the connection is closed. sinedon connection is not closed until it is not accessed. We found this on a Leginon installation on Ubuntu 13 where mysql 5.5 is used. The symptom is that there is only one instance of a particular leginon step is allowed. Therefore, if one user has the Leginon setup wizard opened, no one else can start Leginon properly past setup wizard. If one client is opened, nothing else can have a client connection even if it is not on the same instrument since Leginon saves the client connection event in the database.
