Rob,

Another useful MySQL feature is a user lock.  I use this to
protect object-wrapped table data.

  GET_LOCK(String, timeout)
  RELEASE_LOCK(String)

Obviously, your applications must cooperate within such a
scheme and you're responsible to defining the object lock
namespace, but it works pretty well for me.  Example
application:  ticket dispenser, dispensing monotonically
increasing ticket numbers.
