Hmmm, that's discouraging. Do you know if it's feasible to just keep changes to code in memory synchronised with changes nto the source code? So rather than reload source code, make sure that the source code reflects what is running in memory? For example if your program is running, and you make a change to a class, is it possible to create the necessary class definition and save it to a file?
