Hi, this a hack that should make support for 'libsyck', a YAML Parser in C, possible. Libsyck needs synchronous execution of callbacks, as the memory that is passed back to Parrot is reused by the external library. A callback sub is marked as 'sychchronous' by setting the property '_synchronous' of the user_data to a true PMC. A neater solutin would be automatic detection of safe synchronous execution. When the external library calls the callback, then no callback event is put into the event queue, but the sub is executed immediately. A test is included in t/pmc/nci.t . In src/nci.c the variable names 'user_data' and 'external_data' are now consistently used.
