@devmotion does the Enright DDE test problem set have some good stiff problems?

At least there are no explicitly marked stiff problems.... But http://scholarpedia.org/article/Stiff_delay_equations contains some stiff DDE problems, and even mentions a neutral problem from Enright and Hayashi. However, to me it seems that the Enright test set only contains a similar neutral DDE but not exactly the same.

Some test problems for RADAR5 are available on Hairer's site. Would be interesting to compare DelayDiffEq with RADAR5, but this would require both a Julia interface to RADAR5 (see luchr/ODEInterface.jl#6) and an JuliaDiffEq interface.

I wouldn't bank on it ever happening. But it would be nice to get the same tests as RADAR5 up and running to show we can do it.
