Use a reentrant lock and proceed to double-require?

In our case I think it will be tricky to detect a deadlock, so we're 
likely to emit a stern warning when a require is forced to block and 
then go ahead and block. At least that will give us an idea where the 
circular require lives.

How would C Ruby detect the deadlock?
