Debugging them ranges from impossible (if they're suspected) to hard (if you have a stack trace of one actually happening). At least in the newer JVMs the deadlock detector will actually point out the participants in a deadlock right there in the trace.

I know about this stuff but its just amazing how often you forget it when coding and then have the dreaded task of debugging the application to see what's going wrong. Think about it early and it will save headaches later. Synchronization is one of those things that when it works is absolutely amazing but, you have a greater chance of something going tits up when you are not experienced. Long live Erlang :) Very good and very true.
