this seems like a hack but have you considered createing a file ".session.lock", and have drscheme remove it uppon every boot.  Then have the program load the library if there is no ".session.lock" file, (and after loading it, the program would create the ".session.lock" file).

I've run into the following situation, trying to use DrScheme with a file requiring a module that does initialization of a foreign library: When you hit 'run' in DrScheme, the interaction environment is completely "rebooted", i.e. a module loaded before the 'run' will be reloaded post-run. However, while scheme is effectively in a fresh state, this is not true for the foreign library, leading to it being initialized again and again on subsequent 'run's. Any suggestions (other than requiring the user to explicitly initialize foreign libraries)? Specifically, I have some module code that I would like to run *once* per DrScheme process.
