* Added new API functions call_with_interpreter(), enable_external_threads() and disable_external_threads(). The first can be used to call a C function in a context where the Pike interpreter is available. The other two are used to notify Pike that there are external threads that might be competing for the interpreter lock (e.g. by calling the first function). * Made the Java module use these new functions.
