Actually I just might.  Based on your last reponse I wasn't sure if
you wanted me to make further changes.  Then I got side-tracked wondering
why we even have the 'goto retry' in the dmapi post event - why retry the
write if we get ENOSPC when we don't if dmapi is not enabled?  Could the
write get stuck in an infinite loop?
