I'm taking what I hope will be the last pass at incorporating changes to 
the errors interface at https://github.com/mirage/mirage/pull/729 .  As 
a satisfactory interface here is the last blocker to an API that looks 
substantially like what we'll use in MirageOS 3, I would very much 
appreciate your comments or PRs as soon as you can get them in, and 
certainly by (or during) the MirageOS call on Wednesday which I'll 
shortly be sending the reminder for.
Thanks,
Mindy
