Great Jason, I will put that in the exim README.

While you are at it, can you enhance the educational experience by looking
at the starting wsock problem, using your specially instrumented code. 
Is access to both keys above needed for a successful start?

Can you also confirm that wsock starts correctly under strace even
when there is no access to the keys above? 
Does anyone have a theory for that?

Pierre
