I've implemented an External System for an external build tool. However it can be very difficult to debug when things go wrong due to the fact that project resolution is executed in a background process. I've come up with various hacks - fiddling with MY_SYSTEM.system.in.process in the Registry, and adding VM args in enhanceRemoteProcessing to allow me to debug. But I can't always reproduce what my users are seeing, and it would be really nice to be able to log from the background process. Is this possible? Currently my log messages just disappear.
