I was trying to be fancy with the "-e trace=network" bit.  It looks like the 
interesting system calls aren't captured by "trace=network".

Try this: strace -p <cron pid> -f -o strace.out

Let the error happen, then look in strace.out for a 
write(..., "Address already in use", ...),
look for the syscall just before it that returned EADDRINUSE or 98, look 
operations that happened on the file descriptor that the error happened on.

Those will tell you something about what's going on with that socket.

I don't at all guarantee that this will tell you what you're really interested 
in knowing, but you find out lots of stuff that you didn't know about :-)
